3.7.5

01/01/2008

The Splash screen will now appear at program launch for a minimum of 2

         seconds unless the escape key is struck. A main menu View | Splash

Screen option is now available for those needing additional time;-)

When a client receives a message from a server operator, the server

           address will now appear in the title of the message box displayed

on the client.

The Configure MCP Information dialog position is now saved in the profile.

A Start Minimized General option has been added.

Clients will now ignore UDP originating from unknown host addresses.

The replay delay is now adjustable from the replay status dialog.

When the "Ignore consecutive datagrams with duplicate User Data

         within MCP" protocol option is selected, ignored traffic will now

be sent to the dispatcher display in order to prevent timeouts.

When enabled in the Configure | Options | Display dialog, a signal cleared by a control will now blink until:

<img src="_themes/zero/zerbul2a.gif" width="12" height="12" hspace="15">	a subsequent control takes it down
<img src="_themes/zero/zerbul2a.gif" width="12" height="12" hspace="15">	a clear or out-of-sequence ATCS or ARES indication arrives
<img src="_themes/zero/zerbul2a.gif" width="12" height="12" hspace="15">	any Genisys or SCS-128 indication arrives
<img src="_themes/zero/zerbul2a.gif" width="12" height="12" hspace="15">	an inactivity timeout occurs

         This functionality requires the PC's display
         color depth be set to at least 24-bits (typically called "True
         Color"), therefore, a warning message will be issued when the

dispatcher display is started if the current value is less.

ATCSMon behavior when a Station Name on a dispatcher display is found to be non-unique

         in ATCSdb is documented below:

<img src="_themes/zero/zerbul2a.gif" width="12" height="12" hspace="15">	When the dispatcher display is started, a list of MCP addresses is created for each such Station.
<img src="_themes/zero/zerbul2a.gif" width="12" height="12" hspace="15">	The effective Station address will be dynamically updated from traffic matching any of the addresses in the list once monitoring has been started.
<img src="_themes/zero/zerbul2a.gif" width="12" height="12" hspace="15">	The mnemonic maintenance and plotting dialogs for a given Station will not be available from the dispatcher display until an address is assigned, and then, they will reflect only values specific to the currently-assigned address.
<img src="_themes/zero/zerbul2a.gif" width="12" height="12" hspace="15">	If identically-named Stations actually exist in the monitored area and traffic may be seen from both, it will be necessary to specify the address as the Station name for at least one of the Stations. ATCSMon will retrieve the actual Station name from ATCSdb when the dispatcher display is started. These addresses are excluded from the list of addresses mentioned above.

BCP (office) addresses may now be specified in rules by prefacing the address with "BCP=".

The connections window may now be launched from the system tray icon right-click menu.

MSCOMCTL.OCX version 6.1.97.86 is now included in the distribution,

         therefore, it will not be necessary for users to manually apply the
         updates documented in the Microsoft support knowledge base article <a href="http://support.microsoft.com/?kbid=896559">

896559</a>.

A Select Layout MCP's button

         has been added to the Configure MCP Information dialog which selects
         the addresses of all MCP's matching station names on the current

layout.

The placement and appearance of the dispatcher display capture

         timestamp will now be established in the layout via a text entry
         containing the value "TimeStamp". If no such entry is found,
         no timestamp will appear. If multiple Time Stamp entries are found,

only the first entry encountered in the layout file is honored.

When manually restarting the dispatcher display, the most recent

         controls and indications from active MCP's are accumulated, ordered by

timestamp, and resent to refresh the display.

Genisys and SCS-128 "G" and "S" traffic received

         via DDE will now be translated into their new "g" and

"s" equivalents upon receipt.

3.6.1

06/04/2007

Genisys and SCS-128 protocol processing has been updated to be more

         consistent with the ATCS/ARES implementation model:

Servers now include the currently-defined AAR Railroad Number

             and BCP Zip Code values in the data packet.  If  the
             option to "Ignore Genisys / SCS-128 traffic from MCP
             addresses not in database" is selected, only packets with MCP
             addresses found in the server database are sent to clients. Server
             operators are encouraged to select this option to prevent
             replication of invalid addresses which would otherwise occur,

particularly under SCS-128.

Packet protocol ID values are now "g" and

             "s" respectively, replacing "G" and
             "S".  Packets received from pre-3.5.5 servers will
             be transparently converted to the new format via insertion of the
             current client AAR Railroad Number and BCP Zip Code values. 
             Packets from pre-3.5.5 logfiles receive similar treatment. Packets
             received from post-3.5.4 servers by pre-3.5.5 clients will be

rejected with an "Invalid Protocol ID" message.

The file naming convention for Genisys / SCS-128 logfiles is now

             identical to other protocols, (i.e the AAR Railroad Number and BCP

Zip Code are no longer appended to logfile names).

When replaying files, logfile autorotation is now disabled, as is the dispatcher display inactivity timer.

A Configure | Options | Display option has been added to show a

         warning message at display load time if Station names / addresses on dispatcher displays

are not found in the ATCSdb database.

The .dat extension has been replaced with .log in the Rules | Log file name dialog.

Windows Vista is now a supported operating system.

When displaying multi-part messages, the Packet window will now show "Part n of x" beneath the message number line.

Leading and trailing spaces are now trimmed from IP addresses in the Data Sources dialog.

The Configure MCP Information dialog now contains latitude, longitude,

         and milepost columns, and dialog height, width, and column widths are
         now saved in the profile. Additionally, a Select Active MCP's button
         has been added, which will select all MCP's currently appearing in the

main form MCP pane.

ARES 215.2 Time Update message timestamps are now properly decoded.

DDE Errors are now displayed on the Main Status Bar, in order to

         alert those who have unintentionally enabled one or more of the DDE

outputs.

A splash screen has been added, and the main form is now displayed prior to any diagnostic dialogs.

Fixed a bug in 3.6.0 which caused corruption of the Configure MCP Information dialog.

3.5.4

12/10/2006

EOT protocol has been added. Message type is 0.0.0, which will be

         automatically added to the messages dataset in ATCSdb. Addresses are
         9000XXXXX
         where X is an EOT device ID digit. An EOT Details option has been added to the Main View
         menu, a default EOT FIR filter is available in the supplied
         atcsmon.ini, and a new rule condition has been added which triggers when a

stationary EOT begins moving or a new moving EOT is seen.

APIgid32.dll and Jet Comp.exe are no longer required files, and msjro.dll

        (installed as a part of MDAC) and BCH6345.dll (EOT checksum

calculation) are now required.

ATCS-Genisys MCP's are now reliably identified, and existing incorrectly-identified MCP's will be automatically fixed when encountered in the data stream.

A "Night Mode" View option has been added which will dim

the entire screen (by altering the Gamma correction used by the video

         chip),

and swap the foreground and background colors of the Packet, Messages, MCP, Plot, and Mnemonics windows. If the Night Mode menu item is greyed out,

the video hardware does not support the required functionality.

Errors 5 and 401 occurring during profile loading have been resolved.

The Dispatcher Display now supports Track Builder 3 bitmaps, but in background mode only.

Dispatcher display blocks with misconfigured right/left linkage values are now detected.

Track Builder 3 bitmap resizing is now supported.

7/4 beta error 35601 which occurred during loading of the Dispatcher Display layout has been fixed.

The Dispatcher Display station name indication color timeout value will now be used for the "Other" color.

Totally-empty control or indicaton mnemonics values no longer overwrite existing database mnemonics during MCP imports.

The Jet version included in the Windows 2000 SP4 Rollup is now correctly identified in the About dialog.

GPS COM port selection now lists only configured ports.

MCP import and export file open dialogs now display files in detail mode.

The last used replay, MCP import and export directory names are now saved to the profile.

"OK" logical OR approach indication logic is now

         supported.  Name the block(s) ":xO" in "TB Block Properties
         - General".  The "From Station" and "To
         Station" supply the two station call-up letters.  Specify
         xOK in Mnemonic Maintenance for each of the MCP's.  OK blocks
         will appear as "FromStation-ToStation:xO&quot; on the dispatcher
         display mouseover.  Unfortunately, it will
         be necessary to rename any existing mnemonics using the operator

"O" (i.e. POK - Power Off indication).

Hypertext links are now supported in dispatcher

         displays. Text beginning with "http" will appear as a clickable, underlined link,
          while text with "http" elsewhere will be displayed as a clickable, underlined link to the http target.

For example, the text value "http://www.atcsmon.com%22 will appear as

          http://www.atcsmon.com;  
			the text value "Click here for the group site.http://groups.yahoo.com/group/ATCS_Monitor%22
			will appear as  Click here for the group site.  The

mouse pointer will turn red when over the link hotspot.

A bug preventing the proper decoding of SCS-128 Recall, Execute, Disconnect, and Test messages has been fixed.

Runtime error 126 messages that sometimes occurred on Windows 98 SE if the

         "server sends current controls and indications..." option

was selected have been eliminated.

A bug introduced in 3.5.2 causing ARES indications to be identified

         as controls has been fixed.  Existing MCPs will be automatically updated to
         the ARES control and indication message type defaults of 199.2/9

and 199.13_ values when data is received.

ATCSMon will once again properly terminate upon windows shutdown.

A main menu View | Layout Information option which displays the TB "About Territory" data has been added.

The main Options window will now appear in the Taskbar.

References in layout blocks to non-existent blocks greater than

         the maximum valid block number will now be detected as an error when

the layout is loaded.

Long signal names may now span both the Signal Name and

         Control/Monitor Name fields.  Terminate the value in either field
         with a "+", and the other field will be concatenated to it

when the layout is loaded.

Out-of-service track block controls and indications are now

         supported for traditional (non-BK, non-OK) approach blocks. When
         identifying these bits, use the same name as the approach block, but
         replace the "A" with "X", i.e the out-of-service
         indication bit for approach block 1WAK is named 1WXK, and the control bit is
         named 1WXZ.  Out-of-service approach blocks always appear in blue
         on the dispatcher display, regardless of the condition of the approach

bit.

A quick search feature has been added to the Configure MCP dialog,

         active for address and name searches when either column is the
         selected sort item. The column names are now appended with an
         ascending "^" or descending "v" indicator when

selected for sorting.

Dispatcher display inactivity timeouts are now disabled during replays.

Dispatcher display MCP addresses are now prepopulated

         from the database upon layout load, so right- and left-clicks on
         the station names display the mnemonics dialogs without first
         having to receive data. This required the addition of an MCPName index
         to the MCP dataset, which is done automatically on a one-time basis
         and requires exclusive access to the database. If a station name is
         not unique in ATCSdb, use the MCP Address as the TB station name, and

the station name will be retrieved from ATCSdb at display load time.

Packet counts have been added to the "Servers Connected" dialog.

Client version numbers in the "Clients Connected" dialog now survive display refreshes.

Dispatcher display stations with blank station names are now detected as errors.

Adjustments to initial UDP timing on both client and server instances

         should minimize server UDP wait state time.  Clients connecting
         to servers configured to send current controls and indications should
         receive that data upon connection (i.e. prior to receipt of any

real-time data).

100.0._ is now a supported MCP Control Information Message Number for IDOT indications.

In client mode, per-server packet statistics are now available in the Servers Connected dialog.

In server mode, packet yield / minute is now available in the status

         bar packet count tooltip, as well as in the system tray icon mouseover

display, when minimized.

Message boxes displayed if a plot is requested for which there is insufficient data now auto-close.

Lower-case Station call-up letters are now supported. ATCSMon

         will now automatically update Track Builder from 3.1G to an ATCS
         Monitor-specific version 3.1H which also supports lower-case station

call-up letters when Track Builder is run from the toolbar icon.

Rules may now be sorted by name.

Main window MCP and Messages column order is now saved in the profile.

User-defined dispatcher display mnemonics with

         state values established via VBScript may now be created.

<img src="_themes/zero/zerbul2a.gif" width="12" height="12" hspace="15">	A TB text value of C:3EG=If (1RW AND 1EG) OR (2RW AND 2EG) then 3EG=True else 3EG=False will define mnemonic C:3EG whose state is determined by evaluation of the VBScript expression following the leftmost equal sign.
<img src="_themes/zero/zerbul2a.gif" width="12" height="12" hspace="15">	The Station Name of the call-up letter in the defined mnemonic must be unique in ATCSdb. If not unique, use the MCP Address as the TB Station name value, and the actual station name will be retrieved from ATCSdb at display load time.
<img src="_themes/zero/zerbul2a.gif" width="12" height="12" hspace="15">	The defined mnemonic call-up letter must be unique (i.e., not shared) within the layout.
<img src="_themes/zero/zerbul2a.gif" width="12" height="12" hspace="15">	If the defined mnemonic contains a trailing "K" or "Z", the script will be evaluated only upon receipt of indications or controls respectively, otherwise it is evaluated upon receipt of traffic of either type. In any case, script variables not found in undefined references are evaluated as False.
<img src="_themes/zero/zerbul2a.gif" width="12" height="12" hspace="15">	The defined mnemonic must not exist in the control and/or indication mnemonics for the control point.

<img src="_themes/zero/zerbul2a.gif" width="12" height="12" hspace="15">	The defined mnemonic is established within the script engine as a persistent global variable with an initial value of False. The actual variable names are "v" followed by the defined mnemonic without the colon (i.e. vC3EG in this case), which may be referenced in scripts for other control points.
<img src="_themes/zero/zerbul2a.gif" width="12" height="12" hspace="15">	If the "clear indications" inactivity timeout option is selected and a timeout occurs, the defined mnemonic is reset to a False state.
<img src="_themes/zero/zerbul2a.gif" width="12" height="12" hspace="15">	The script expression must contain only valid VBScript, and multi-line statements are acceptable. A help file describing VBScript syntax is available here.
<img src="_themes/zero/zerbul2a.gif" width="12" height="12" hspace="15">	These special text entries are displayed only on the TB dialog and never appear on the dispatcher display.
<img src="_themes/zero/zerbul2a.gif" width="12" height="12" hspace="15">	To aid in script debugging, if the CTRL key is held down while restarting a dispatcher display, all detected scripts will be displayed in message boxes during dispatcher display load, as will the evaluation of the scripts during execution. Additionally, all text entries will be displayed in the raw text window.
<img src="_themes/zero/zerbul2a.gif" width="12" height="12" hspace="15">	The Microsoft Script Control MSScript.ocx, available here, is now a required file.

Up to 30 server addresses may now be specified in the Configure | Options | Data Source | Network Settings dialog.

ATCSMon will now terminate properly during system shutdowns.

         Additionally, if the main window is manually closed or the main menu
         Exit option is selected and the save settings dialog is displayed,

operation will continue normally if the Cancel option is selected.

The zoom button is now enabled when new plots acquire more than 2 data points.

Plots launched from the dispatcher display will no longer occasionally initially display in a zoomed mode.

Logical active text, broken in the 6/19 beta, is once again functional.

Any mnemonic defined for an MCP may now be used in Active text

         entries. Previously, standalone active text mnemonics had to be
         user-defined, requiring specification of a logical value if a defined
         mnemonic needed to be used.  For example, 
         A:1RG&1RG=text-to-display may now be specified as
         A:1RG=text-to-display if 1RG is defined for the MCP in Mnemonic
         Maintenance. If 1RG is not defined for the MCP, text-to-display will

of course be evaluated as VBScript.

Active text now operates reliably when shared station call-up letters are specified.

An option to log but ignore decoding errors has been added to the General Options dialog.

mms:// and rtsp:// may now be specified in dispatcher display hyperlinks.

The dispatcher display may now be scrolled with the keyboard arrow keys.

Error 13: Type Mismatch errors that occurred when no text entries were specified on a dispatcher display have been eliminated.

The messages window will now display text userdata for ATCS 60.2.11 messages when text is present.

The main menu Help FAQ item has been replaced with a link to the new Wiki Documentation Project.

ATCSdata.dll has been updated to version

         3.5.4, eliminating divide-by-zero errors that occurred in very rare

cases when packet header checksums failed to detect errors.

Dispatcher display switch

         out-of-correspondence (switch-in-motion) indications now operate
         properly for switches defined in TB with lock mnemonic overrides

(i.e., "A:1NW,A:3LZ").

Hostnames may now be specified in the Server

         Mode IP address fields, facilitating denial of server access by

software router applications.

ATCSMon will now terminate gracefully at startup if MDAC or Jet are missing or misconfigured.

Numeric columns in the Active MCP Window are now sorted correctly when clicked.

The Progress Bar displayed when replaying text

         logfiles is now a Slider, which permits movement to any location in
         the logfile being replayed, and packet timestamps are now displayed at

the top of the dialog.

Windows Installer has been replaced by

         Inno Setup, therefore it is recommended to back up all user data
         (profiles, layouts, ATCSdb, etc.), perform an uninstall of any
         previous version and remove the installation directory before
         installing this version. After installation, restore user data from
         the backup.  Issues with Windows Installer
         attempting to perform reinstallation under certain circumstances are
         of course eliminated when this procedure is followed. From this
         release forward, only a single installation file will be provided
         which can be used for both new installs and updates.  When

updating an existing installation, all user data is preserved.

3.5.2

06/12/2005

<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	Fixed a plot bug that occurred when the 2.3.1/3 control message type was specified.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	Added a General option to enable addition of Locomotive MCP addresses to the database. MCP name will default to AAR Railroad Abbreviation (reporting marks) and unit number, and names for existing addresses will be updated only if blank. Both 10- and 14-digit addresses are supported.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	The Genisys / SCS-128 BCP Zip Code protocol option has been split into the actual Zip code and suffix.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	The default file naming convention for Genisys / SCS-128 logfiles is now yyyymmddhhMM_RR_ZIP.log, where RR is the 3-digit AAR Railroad number, and ZIP is the BCP Zip Code and suffix. Upon replay, the current AAR Railroad number and BCP Zip values are derived from the filename.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	XOR ("^")is now a supported active text operator.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	A port count value has been added to the server base port parameter for UDP communications in the Network Settings \| Server Mode Listener Notes field. Specify "Base=26000,100" to limit the assigned ports to 26000 through 26099. Minimum count value is 3, maximum is 100, and a default of 20 is used if a valid value is not supplied. Minimum port value is 1024, maximum is 65000. When present, base values now appear in the Clients Connected window caption. Set this option only if your firewall requires manually-established rules for inbound UDP, or if you wish to limit the number of concurrent client connections, since connection attempts exceeding the limit will be rejected.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	The Packet window horizontal scrollbar will be located leftmost after retrieving stored traffic.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	Frequency and Protocol columns have been added to the Configure MCP Information window, and it's caption will now display the current ATCSdb path.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	Database compression now functions properly on Win9x platforms.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	199.2/9 and 199.13_ (signifying 199.131 and 199.136) are now supported ARES MCP Control and Indication Message values, and will be supplied as defaults for new MCP's.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	Message snapshots are once again replayable (broken in 3.5.0).
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	The "Open new capture file at 12:01" option now applies to rule-based logfiles as well.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	Navigation buttons have been added to the plot window. To zoom to a selected area, use buttons or click and drag the mouse across the desired points. When zoomed, plot updating will be suspended although no data will be lost. Updating will resume when plot is zoomed fully out. Keyboard arrow keys, Page UP, Page Down, Home, and End keys are mapped to button functions.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	Graphlite.ocx is no longer required and has been removed from the distribution.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	A Protocol option to ignore locomotive packets has been added.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	Blocks named StationCallupLetter:Dead will appear in gray on the dispatcher display, and may be toggled between dark red and gray when clicked.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	Run-time error 9's that occurred when clicking another application while a dispatcher display was active have been eliminated.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	Track elements obliterated by Active text are now restored when the text becomes inactive.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	ATCS Inbound ACK's are now properly identified.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	For those of us who enjoy fishing through packet contents with a hex viewer, snapshot capture files created with a ".raw" extension now contain non-replayable binary data.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	Packet window maximum message count is now user-configurable, defaulting to the previously-hardcoded value of 30. Use of large count values may result in sluggish operation during monitoring unless the "Hold Packet Display" toolbar button and/or new "Save decoded data" option is selected. Monitor CPU usage to determine an appropriate value for your machine.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	An option to Save decoded data has also been added which saves the formatted packet window text for each packet to the traffic array, resulting in much quicker refreshing of the packet window (read: faster MCP window navigation when running with large message count values) at the expense of substantial memory usage.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	The setting of the Hold Packet Display toolbar button is now saved in the profile, useful for server configurations.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	When selecting MCP's in the Active MCP window, the mouse icon now changes to an hourglass while the packet window contents are refreshed. Richtx32.ocx is now a required file.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	Keepalive error messages are now suppressed when the socket is in the connecting state.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	Minimized plots may now be successfully closed from the taskbar right-click menu.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	Those who update using upgrade components rather than re-install may need to overwrite riched32.dll in their ATCSMon installation directory with the supplied version if the packet window hex dump displays incorrectly.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	The "Always on Top" dispatcher display and plot window title bar right-click menu options no longer disappear after the windows are restored from a minimized state. The redundant Configure \| Options \| Display \| "Dispatcher display is always on top of other forms" option has been removed. Plot and dispatcher display window "on top" option reliability is improved.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	Separate Dispatcher display inactivity timeout values for controls and indications are now available, useful for assigning a longer timeout when only controls are received for some MCP's.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	Mnemonic maintenance no longer accepts standalone "K" or "Z" values.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	The "Clear messages and replay MCP data" Active MCP window right-click menu option has been moved to the bottom of the menu.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	BCP ID is now appended to the MCP Address value for CSX 107.4.3 messages.

3.5.0

11/01/2004

<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	X-axis labels on MCP data plots no longer overlay during resizing.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	General options have been added to limit the number of plot points and enable/disable automatic plot height updating.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	Plot and Mnemonics window location coordinates are now saved in the profile.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	Minimized plots now remain minimized.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	In mnemonic maintenance, bits which have seen a non-zero value during monitoring (or replay) are now shown in red if unnamed and blue if named. The bit history values for controls and indications are stored in new ATCSdb MCPActivityC and MCPActivityI fields. Bit history values are cleared when the "Clear bit history" options are selected, or when protocol, indication bits, or control bits values are changed.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	A new rule condition allowing selection of control and indication messages with active but unnamed bits has been added.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	FTP transfer routine for transmission of dispatcher display image capture files now recovers from dropped connections more reliably.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	Dispatcher display station activity timestamps now appear in the station name control/indication colors.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	Added Select All Messages and Copy from Message Window (to clipboard in tab-delimited text format) to main form Edit menu.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	AAR_P1_Functions entries in profile (.ini) files will be transparently copied to a new P1Functions ATCSdb table. The entries and section header are deleted from any profile when saved.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	When MCP updates are imported in the Configure MCP Maintenance dialog, the original MCP record is now stored in a new MCPRollback table. Use the new Rollback/Undo button in the Mnemonic Maintenance dialog to restore the mnemonic values from the MCPRollback table.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	Servers will now send the most recently received control and indication for each MCP to clients at connect time if the new General option for this feature is selected.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	MCP information will be added to the ATCS database for all packet types (with non-loco addresses). Previously, only addresses appearing in datagram packets were saved.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	Client ATCSMon version number now appears in the server's "Clients Connected" dialog and server logs for 3.4.9 and greater clients.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	Toolbar shortcuts have been added for Configure MCP Information and Start/Stop Capture to FIle.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	Sound Card Device Name is now saved in the profile when data source is Sound Card, and ATCSMon will now first attempt to open devices by name, then by number.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	The middle mouse button will now launch plots from the Dispatcher Display.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	The default DDE relay and DDE data source server and topic values of 'DDEServer' and 'DDETopic' may now be overridden with a new General option. When selected, the values will be set to 'Srvxxxx' and 'xxxx', where 'xxxx' is the Server Mode Listener port value, allowing server operators to establish the level of upstream-to-downstream consolidation. So, if you've got four instances upstream that you want to consolidate to two publicly-available downstream ports, configure upstream instance 1 and 2 for 4800, 3 and 4 for 4801, downstream instance 1 at 4800, and 2 at 4801. To have all 4 upstream instances available on a single downstream feed, then configure all instances with the same listener value or simply deselect the option. If you are using one of Larry's external decoders and require this option, contact Larry for an updated version.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	FSK (Genisys and SCS-128) demodulation is now performed within VB. Expect significant improvements in packet yield for 1200 baud 202T, minor improvement in yield for 300 baud 202T, and equal yield in RFL. Optimize yield by enabling or disabling FIR filtering. Distribution ATCSMon.ini contains new default FIR filters. Machines with very slow CPU's may exhibit buffer overflow messages.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	Since Genisys and SCS-128 protocols use unverified (no CRC) single-byte station addresses in some message types, invalid addresses (values with good parity and framing but invalid for a given BCP) are often seen and automatically added to ATCSdb. A Protocol option has been added to ignore any Genisys/SCS-128 traffic for addresses which do not exist in ATCSdb, preventing addition of invalid values. Leave the option disabled when initially monitoring until the valid addresses can be determined, then delete any invalid addresses in MCP Maintenance, and select the option for subsequent monitoring.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	Microsoft Jet Engine version now appears in the About dialog.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	Dispatcher Display resizing now works with very large displays.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	DIspatcher Display station names are now assigned independent activity timers, improving display accuracy.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	The error dialog option to supress display of further errors has been removed. Select Cancel on the dialog to terminate ATCSMon, or OK to ignore the error and continue execution.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	ATCSMon will now terminate if ATCSdb cannot be found in the specified database path or in the installation directory.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	Files scrwin.ocx, mmtty.exe, mmtty.ini, and User Para.ini are no longer required and have been removed from the distribution.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	Added a Dispatcher Display option to allow non-control/indication traffic to change the station name color to a user-specified value. The change will occur only if the current station name color is the default value (i.e., not currently shown in the control or indication colors).
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	Added message-specific decoding for message type 100.0.2 IDOT Indications.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	2.3.1/3 is now a supported 5-series MCP Control Information Message Number.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	Version information in the About dialog may now be copied with Control-C.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	In MCP Maintenance, control and indication bit counts now update properly when the protocol value is changed from ATCS to ATCS-Genisys.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	Fixed overflow error when using Capture interval greater than 30 seconds.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	Intervals in excess of one minute during which no packets have been received will now appear in server logfiles with a status of "Stall".
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	Note: All required structural changes to the ATCSdb database are performed automatically, therefore no new database is necessary for this release. Updated databases are not compatible with pre-3.4.9 versions, however, MCP exports from post-3.4.8 versions in either .mdb or .mcp format may be imported into earlier versions. In order to eliminate any pre-existing ATCSdb corruption that may prevent these updates from correctly executing, ATCSMon will now automatically run Microsoft's JetComp compress/repair utility if it opens a pre-3.4.9 database. The utility is now included in both (full and upgrade) distributions, must be present in the ATCSMon installation directory, and must have exclusive access to the database. A new "Compress ATCS Database" option has been added to the Actions menu to facilitate manual database compression. During the compression process, the original source database is retained as ATCSdbyyyymmddhhmmss.mdb in the current ATCSdb path.

3.4.8

04/11/2004

<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	A dispatcher display option has been added to clear all non-switch indications at an MCP when resetting the Station Name color due to inactivity.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	Signals may now be selected for clearing based upon a logical AND of specified switch setting values, i.e., if signal A:4LG is to be selected only when switch values 1NW, 2RW, and 3RW are active, specify "A:4LG/1N&2R&3R". (The trailing "W" is dropped due to TB signal name size constraints.) The earlier method of signal selection via prioritization (see 3.0.5 release notes) remains supported.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	A "Copy" button has been added to the "Configure MCP Information" dialog.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	Rules may now be triggered by a logical AND of mnemonics in the "Mnemonic Matches" field, i.e., specify "1RAK&1TK" to trigger a rule when both 1RAK and 1TK become concurrently active.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	If the Rules \| Log Messages to File filename is an executable file (.exe extension), that program file will be executed with a command-line argument equal to the Rule Name whenever the rule fires.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	Replay filename will now appear in the replay Status dialog caption, and the last filename replayed will now be visible in the toolbar replay button tooltip text.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	When opening a profile containing no ATCSdb location, the database in the installation directory will be used. Previously, any currently-opened database was used in error.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	Replay file open dialog will now display in "Details" mode rather than filename mode.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	An Apply button has been added to the Mnemonic Maintenance dialog.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	Mnemonic changes are now propagated to active plots.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	The "P" key will now launch a plot for the selected MCP in the Active MCP Window.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	Server logfiles now contain additional state information to assist in diagnosing connectivity problems.

3.4.6

01/12/2004

<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	Switch Indications with identical NW and RW bit values (i.e. NW:0 and RW:0, or NW:1 and RW:1) now cause the switch to be outlined on the dispatcher display in the color selected in the new "Switch in Motion color" option. Active switch locks take precedence over switches-in-motion.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	Dispatcher display switch position is now updated only when the NW and RW bits are unequal. Therefore, switches are no longer set to RW if the Test button is clicked when no switch bits have been set.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	Inverted mnemonics now default to the selected state (yellow) in Mnemonic Maintenance.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	TB station names and MCP names must now be identical (except for case).
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	ARES source and destination addresses with zeros encoded as "A" are now decoded correctly.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	An "Enable Relay Output" DDE option has been added. Active only when the data source is Network, this produces a raw data output compatible with the DDE data source option.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	Dispatcher display conditional "active text" mnemonics now operate correctly at stations using shared station call-up letters.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	Error dialog captions are now set to the main form caption for easier identification of the instance in error.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	Packets causing display of an error dialog are now logged to the logs directory as yyyymmddHHMMSS.err
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	Server logfiles now carry an .slg extension rather than .log.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	GPS settings have been moved to the renamed "DSP/GPS" tab.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	File directories such as MCPs, Logs, etc. may now reside either in the installation directory or ATCSdb Path, selectable via new option buttons in the Configure \| General dialog.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	A General option to create new auto-capture log files each midnight has been added. When selected, log file names include profile filename and date in yyyymmdd format, i.e. "currentprofile20031225.log".
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	Overflow errors occurring on dispatcher displays containing many active text fields have been fixed.

3.4.4

10/22/2003

<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	Data Source Sound Card and COM Port options dialogs have been combined to provide more real estate for Network Settings.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	Messages and Active MCP window fonts are now selectable.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	The plot "Always on Top" setting may now be changed from the display's title bar right-click menu.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	An option has been added to the "Station Names retain last color" feature that causes station names to revert back to their original color after a specified period of inactivity. A zero value deactivates this option.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	Version information in the About dialog is now copyable.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	Dispatcher display mouseovers now appear in a fixed location for each Station, and the Ctrl key now displays all mouseovers simultaneously.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	Added message-specific decoding for ATCS type 107.4.3 CC_ID_MSG.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	Dispatcher display title bar caption will now contain only the TB Territory Name when nonblank.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	The Escape key will now close the currently-active child window.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	Added Builder Toolbar option to edit current dispatcher display layout.

3.4.3

10/05/2003

<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	The Packet Window will now display all saved traffic for the selected MCP without truncation.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	Packets which are neither controls nor indications have been eliminated from plots created from data in the Active MCP and Messages windows.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	Genisys and ATCS-Genisys plot points for partial indication packets have been corrected on plots invoked from the Active MCP window
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	The Plot display may now be dragged by clicking on any area outside of the plot itself, not just the title bar.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	Broadcast Type 01 messages are now decoded as 2.3.4 Indication ACKs.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	In client mode, server connections are now handled independently. If a server cannot be initially reached or an operating feed fails, all other feeds continue to operate normally. If auto-reconnect is specified, only failed feeds are restarted.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	Server IP address and port number have been added to the "Network Error" dialog.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	Servers will now terminate client connection attempts if the connection sequence is not completed within 20 seconds.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	An option to view the server connections log has been added to the main menu "View" option.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	Session termination status information has been added to the server log.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	Connection counts have been added to the system tray mouseover display.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	Non-essential files in the ATCS Monitor distribution are now tagged as optional in the .msi file, so that their removal will not trigger automatic re-installation by Windows Installer.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	Railroad abbreviation lookup now uses the AAR railroad number from the MCP address only.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	System responsiveness is much improved during replays with nonzero replay delays, and when replays are paused.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	Added Finite Impulse Response (FIR) filtering option for both sound card input and wave file replays for ATCS, ARES, and 202T modulation. Select the DSP (Digital Signal Processing) tab on the Configure \| Options dialog to enable filtering and configure filter tap coefficient values. Filters should have odd tap counts, and must have from 11 to 299 taps to be considered valid. Filters may be imported from the distribution atcsmon.ini, or use a freeware tool to design your own and use the Edit button to import the values via cut-and-paste. The Edit dialog will accept values in the format "tapname=value" or simply "value". A downloadable FIR filter designer may be found at dazyweblabs.com, or search the web for "fir filter design" and use one of the many many free Java applets available. WARNING: Substantial improvements in ARES and 202T packet yield have been seen during testing, however, poor filter design can certainly degrade yields. Using a filter with ATCS modulation is not recommended at this time. To evaluate the effectiveness of a filter, record a .wav file of representative audio and replay it with the filter enabled and disabled and compare the results. New DLL nbfir.dll is REQUIRED for this release.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	The dispatcher display "Always on Top" setting may now be changed from the display's title bar right-click menu.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	MCP names for auto-added 7-series ATCS MCP addresses ending in "01xx" will now be automatically created from the "0202" or "0102" address name suffixed with "c/c".
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	Active text mnemonics are now sorted by state (off first, on second) prior to processing by the dispatcher display, which is consistent with other mnemonic types.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	Profile files greater than 32K but less than 64K are now supported on NT or later windows versons. If a profile greater than the supported length for the version in use is opened, a warning message is issued.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	Profile progress status display now appears whenever profile data is saved.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	Dispatcher display visibility status is now saved in the profile.

3.4.0

07/27/2003

<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	Corruption of the Network Settings dialog that occurred after an address was added as been fixed.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	Corruption of dispatcher display crossover colors has been fixed.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	Corruption of the main display that occurred when the application was restored from the system tray has been fixed.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	TB Station Name and Text colors with corresponding RGB values greater than 65535 now display correctly.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	At least one Hostname / IP address must be enabled in the Network Setting dialog in order for monitoring to be started if the selected data source is Network.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	The annoying beep that occurred when sending messages from the messages window to the dispatcher display via the "s" keystroke has been eliminated.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	The Mnemonic Maintenance tab order is now from right to left, mnemonic text is automatically highlighted (selected), and the "OK" button is now the default action when the Enter key is pressed.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	User-defined mnemonics (without the leading "$", but ending with "K" or "Z") may now be entered in Mnemonic Maintenance. These may be used to control dispatcher display text by setting the text value in TB to StationCallupLetter:UserDefinedMnemonic=DisplayedText, remembering that TB Mnemonics do not carry the trailing "K" or "Z".
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	It is also possible to specify two mnemonics separated by "\|" (logical OR) or "&" (logical AND) in TB in order to facilitate logic-driven text messages. For example, to create a text message for a location that uses opposing cleared signals to indicate plant-in-time, specify a TB text value of "StationCallupLetter:1LG&1RG=Plant in Time" to display "Plant in Time" on the dispatcher display whenever both 1LG and 1RG (in either controls or indications) are active at the MCP. Support for the "PL" base mnemonic (which caused the Station Name to be displayed in yellow when active) has been withdrawn.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	Switch lock ("LZ" and "UL" base mnemonics) status is now shown on the dispatcher display as a color outline surrounding the switch when active. Specify xLZK or xULK in Mnemonic Maintenance, which will automatically associate with the TB switch named X:xNW; if it is necessary to override this default behavior, name the switch "X:yNW,X:xLZ" or "X:yNW,X:xUL" in TB, where "X" is the Station Callup Letter. Outline color is selectable in the Options \| Display dialog.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	"BK" approach indication logic is now supported. Name the block(s) ":xB" in "TB Block Properties - General". The "From Station" and "To Station" supply the two station call-up letters. Specify xBK in Mnemonic Maintenance for each of the MCP's. BK blocks will appear as "FromStation-ToStation:xB" on the dispatcher display mouseover.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	The "Servers Connected" dialog now displays the server-assigned remote port number for UDP communications.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	The "Clients Connected" dialog now displays the server-assigned port local port number and the client's remote port number. A "UDP" column indicating "Wait" if no UDP has been received from a client or "OK" if UDP has been received has also been added.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	The server base port number for UDP communications may now be specified in the Network Settings \| Server Mode Listener Notes field in the format "Base=26000", facilitating establishment of firewall rules for inbound UDP. The port numbers assigned to clients will be the sum of the base value and the connection index. Set this option only if your firewall requires manually-established rules for inbound UDP.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	When the packet display is held and the current message window sort sequence is by ascending time received, the messages window will no longer scroll but will continue to be updated.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	"Analyze Signal" and "Data Sources" toolbar shortcuts have been added.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	MCP plots now display control and indication data points only on their respective lines. Previously, a data point was plotted on every line for both controls and indications. Additionally, gray horizontal grid lines and right-side mnemonic legends have been added. A new Graphlite.ocx is REQUIRED for this release.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	Plots may now be launched from the dispatcher display with a shifted (actually Shift, Ctrl, or Alt) right or left click on the station name when the station name mouseover is visible.

3.3.2

01/24/2003

<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	All known dispatcher display resizing issues have been fixed. An updated Scr Win.ocx is REQUIRED for this release.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	MCP data exports are now optionally produced in .mdb (Access database) format to eliminate the 32K restriction inherent in .ini-format output. Files named with .mdb extensions will be handled as Access databases and any other extension will be processed as an .ini on both import and export.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	The Connections window is now maintained in real-time, and a main menu "View \| Connections Window" option has been added.

Overflow errors caused by uninitialized array elements in dispatcher display layout files have been eliminated.

3.1.3

03/31/2002

<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	Configure \| Options \| Display dialog has been reorganized, and now contains a Dispatcher Display Options frame. Replay Delay setting has been relocated to General options dialog.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	A new Dispatcher Display option has been added to "Reset cleared routes using occupancy indications only". This causes cleared routes to remain green when the clearing signal drops, and will provide more realistic dispatcher displays in cases where indications are reliably received, and all intermediate blocks are named (i.e. controlled via occupancy indications). Be aware that unnamed blocks will remain green forever if this option is chosen. To exempt routes cleared by signals at individual CP's from this behavior (i.e. a CP for which only controls are received), a "Reset cleared routes to white upon signal drop" option has been added to the Edit MCP Information dialog, and the Structure field has been sacrificed. Note: Manual clearing of a signal will continue to set the cleared route to white.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	Manual resetting of crossover color on Dispatcher Display now works correctly.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	If no audio buffers are seen from an active sound card driver within a two-second interval, the driver is automatically re-started, permitting continuous operation with dysfunctional drivers. Nonzero restart count is displayed upon mouseover of toolbar Stop button.

3.1.1

03/16/2002

<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	Closely-spaced (within 185ms) ATCS packets are now correctly received. Previously, only the last packet was received. Updated ATCSdata.dll version 3.1.1.1 contains this fix.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	Commentary Mnemonic values beginning with a dollar sign ("$") may now be entered in the Edit Mnemonics dialog. These will be ignored by the Dispatcher Display, but will appear in all other windows.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	"Play sound" and "Emit beep" rules actions are now enabled during capture replays.

3.1.0

03/10/2002

<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	Mnemonic instance designations may now include zero and A-Z in addition to 1-9.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	Mnemonic values in the "Edit Mnemonics" dialog are now fully validated. Acceptable base mnemonics for both controls and indications are Signal clear (LG, RG, NG, SG, EG, WG), Switch settings (NW, RW), Snow Melter (SM), Maintainer Call (MC), and Switch Lock(L). Additional values for indications include Approach occupancy (LA, RA, NA, SA, EA, WA), Interlocking occupancy (T), and Power Off (PO).
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	Track Builder 3 Control/Monitor values will be used if present, otherwise, the name field value is used.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	DDE input via DDEML API is now available on the Data Source dialog, which accepts valid packets for any of the supported protocols. E-mail me for additional details if you wish to use this feature.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	If Dispatcher Display switch occupancy is manually cleared, switches will subsequently appear in the proper color.

3.0.7

03/02/2002

<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	ARES data slicer input now operational, however, sound card input provides best packet yield. New 3.0.7.1 version of ATCSdata.dll is REQUIRED for proper ARES slicer operation.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	Added "Mnemonic matches" field in Edit Rule dialog. Either a single mnemonic value or a mnemonic mask may be enteredВ (i.e. "AK" would match any approach at a CP, "LAK" would match any left approach, "1LAK" would match only that approach).В The rule will trigger only for an "off-to-on" transition of any matching mnemonic in the control or indication packets for the specified CP. Useful for approaching train alerts, etc. If contact closure is needed to control external device, use "Play Sound" option and connect soundcard output to external VOX circuit.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	When data source is sound card, "Play Sound" rule option now works, if full-duplex sound card is present.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	When replaying capture files with the "Replay Delay" option set to 10000 (prompt), the "Next Record" message box now appears on top of (rather than behind) the progress bar window.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	Invalid characters in Mnemonic values in the "Edit Mnemonics" dialog are now rejected.

3.0.5

02/15/2002

<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	The Dispatcher Display is now available in an intermediate size (right click to change size), and the selected size is saved in the profile.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	Scroll bars will now appear on Dispatcher Display if the layout exceeds the screen size, or the display window is sized smaller than the layout.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	Dispatcher Display station names finally appear as located in Track Builder, which may require adjustments to existing layouts.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	For signals that are selected for clearing via switch settings , the full switch name may now be specified following the slash (i.e. names such as A:1RG/2RW, A:1RG/3RW, and A:1RG/1NW are now supported). When a clearing mnemonic arrives, signals are evaluated in order of the specified switch name (lowest to highest i.e. A:1RG/1NW, A:1RG/2RW, and A:1RG/3RW). The first signal with a matching switch setting is selected, thus permitting selective clearing of any signal in the group. This may require renaming the switches themselves in order to establish the proper prioritization. The 4way.lay in the 3.0.5 distribution demonstrates proper naming.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	In order to easily test Dispatcher Displays, a "Test" button has been added to the Mnemonic Maintenance dialog. To use this feature, double-click the mnemonics to set the desired state ("On" values become yellow, "Off" values are white), then click the Test button to send the selected settings to the dispatcher display.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	The "Display Control and Indication mnemonic values in dispatcher display" option in the Configure \| Display dialog has been replaced with an option to disable the Dispatcher Display "Always on Top" feature.

3.0.0

01/20/2002

<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	Track Builder Version 3 Dispatcher Display layouts are now supported. However, it appears that manual naming of "Connector" (formerly "dummy") blocks is no longer possible (as of TB3 version 3.1E).
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	Windows XP is now a supported operating system.

A "Pause" button has also been added to the replay status display. Captured logfiles will now contain only the replay information, resulting in far smaller file sizes.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	The Railroad Information dataset has been updated with more current information, and an "ATCS in Use" (RRATCS) field has been added.

<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	When using N, S, E, and W directionals in signal naming, "W" means "a signal visible to westbound traffic, not the signal at the west end of an interlocking. However, approach blocks are generally named based upon their physical location at the CP, i.e. "W" means the west side approach. ATCS Monitor will now create default approach block names accordingly if the associated signal has a N, S, E, or W name.

         server by entering the servername, username, password, and
         targetdirectory in the Capture Path
       field.  Once established, the FTP connection is persistent, eliminating recurring connection overhead.  If the connection is lost,
         a reconnect will be automatically attempted at the next capture
         interval, allowing ATCS Monitor to continue unattended operation in
         the event of web server outage or maintenance.  Image filename sent is

2.5.4

02/06/01

<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	Added periodic Dispatcher Display screen capture JPEG output, permitting auto-refresh of display images for web servers. See Configure \| Options \| ATCS Data for details. (Note: This feature currently only works on NT systems.)
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	Fixed distortion of CP names on dispatcher display that occurred in some cases when small fonts were used.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	Fixed error on MCP Import if non-existent filename was entered in file open dialog.

<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	Fixed Winsock Error 10054 - Remote Reset which occasionally occurred when running ATCS Monitor in server mode on Windows 2000 Professional.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	Re-labeled Mnemonic bit columns in accordance with industry-standard nomenclature.

2.5.2

12/31/00

<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	Mnemonics containing any lower case letters are now supported as "active low", i.e. a zero bit value is considered the "on" state, and a bit value of "1" is the "off" state.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	Fixed overflow error that occurred if more than 32767 messages were logged for a given MCP.

2.5.1

12/19/00

<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	Dispatcher display now shows tooltip containing mnemonic name of any named block, signal, or switch upon mouseover. Useful for debugging displays and to verify default approach and interlocking block assignments made by ATCS Monitor.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	When manually clearing dispatcher display blocks, all identically-named blocks are now simultaneously cleared.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	Fixed error that occurred if "Plot MCP data" was selected while plot window was minimized.

2.5.0

12/03/00

Added sound card device name to the Configure | Options | Data Source dialog.

         This allows separate instances of ATCS Monitor to be run on a single PC,
       each with input from a different sound card.  Useful for server installations
       where it is desirable to monitor more than one radio frequency.  Also useful when a composite MCP and BCP display is desired from a single PC. 
         This may be accomplished by running 3 instances of ATCS Monitor simultaneously: 
       two instances each monitoring a different radio via different sound devices, and 
       the third instance listening to the other two via "localhost" network addresses. 
         (Allow at least 150Mhz of CPU per instance for best results,
       however.)  Also suggest using different models of sound cards, since in my experience

it is unlikely that two identical sound cards will co-exist due to poor driver design.

2.4.7

11/26/00

Fixed a problem in the Dispatcher Display where interlocking

       track occupancy ("TK" mnemonic) was incorrectly displayed under

certain circumstances.

2.4.6

09/25/00

Added tooltip showing last traffic timestamp for each CP upon mouseover of CP name on Dispatcher Display.

2.4.4

09/23/00

<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	If a switch has a cleared route over it, and incoming traffic would change the switch setting, the Dispatcher Display now will unclear the route by setting the clearing signal to stop, then changing the switch setting. This will keep display weirdness to a minimum when traffic has been missed. This feature also works when manually manipulating the display with the mouse.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	All switches with the same name are now set with a single mouse click on any one of the identically-named switches.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	Clickable elements of the Dispatcher Display are now indicated by a yellow box when navigating the display with the mouse.

2.4.3

2.2.0

06/07/00

<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	MCP Data Plot function added. Very handy for reviewing codeline indication bit change patterns. A right-click on an item in the messages window will plot all traffic for this MCP with this message type from selected message to last qualifying item in window.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	Replay MCP traffic to messages window feature added. Some ATCS Monitor functionality is only provided for messages appearing via rules selection in messages window. A right-click on an item in the Active MCP window now provides the option to clear the messages window, and replay stored MCP traffic against the current ruleset in order to re-populate the messages window.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	User datagram field in message window now displays codeline values in both binary and hex for message types 2.3.1 thru 2.3.4.

<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	Specification 250 message names are now displayed instead of P1 message type description if the message number is found in the messages database.

2.1.0

05/20/00

<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	Added Reed-Solomon Forward Error Correction (FEC).

1.5.0

03/23/99

<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	Added activity indicator to right-side of toolbar. A green LED lights whenever data is received. LED lights for about a half a second after the last packet was received. LED is not visible when no data is being recieved. The LED can be turned off via an option in the View\|Options window.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	The status bar message now returns to "Monitoring" if no new traffic received in three seconds.

1.4.1

03/01/99

Made "Analyze Signal" available when using the RM100 decoder, accidently left it disabled in version 1.4.0.

1.4.0

02/27/99

<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	Added "Clear All Windows" menu item to the Edit menu. This menu item clears the contents of the Messages, Active Terminals, and ATCS windows. Useful when you switch which system you're monitoring while the program is running.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	Added "Emit beep through computer's speaker on match" option to the window used to define what happens when a rule match is made. It's possible this won't work for everyone, it works for me though. I think some computers may intercept the beep and send it to the sound card instead.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	Added ability to specify the foreground and background colors of the alert windows opened based on rule matches. To specify the colors to be used click on the "Configure" button to the right of the "Display message in pop-up window" checkbox.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	Doubled the size of the COM port buffer used when using the RM100 decoder for the reception of ATCS data. This was done to decrease the chance of buffer overruns when Windows doesn't give the ATCS Monitor enough attention (when other programs are starting up or are doing other things).
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	Added the ability to import and export rules to/from files. The "Export Rules" and "Import Rules" buttons are in the "Configure Rules" window.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	When the program loads and no rules have been setup the program will add a sample Datagram rule for you. The sample rule will display all datagram traffic in the Messages window (the big window at the top of the main window).
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	Added a right-click menu to the MCP Aliases window. The window contains one item: "Assign/Edit Aliases." This does the same thing as double-clicking on a MCP Address. Both are used to assign an alias to a MCP Address.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	Added a right-click menu to the main form that can be used to hold the packet display so you can read it. To open the right-click menu containing the "Hold ATCS Display" click the right mouse button in the grey area between the top and bottom windows, betweem the left and right windows at the bottom of the main window, or on the toolbar or status bar. This was added to make it easier to hold the packet display, now you don't have to move the mouse as far to hold the display.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	Replaced the virtual device driver, slicer.vxd, with a newer version. This driver is used when using a data slicer to get ATCS data. From the author of slicer.vxd: There's a new bug free (I hope) version of the Vx D that will support shared interrupt vectors and also should have fewer problems with unloading itself when errors are detected.

1.3.0

02/04/99

<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	Added printing capabilities... You can now have all received traffic sent to your default printer (select "Capture To Printer" from the File menu) and setup rules to have selected traffic sent to the printer.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	Added a "Copy Rule" button to the "Configure Rules" window.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	Modified routines used to save profile information to save MCP aliases and rules only if they've been changed.

1.2.0

01/30/99

Added an option to the "Data Source" tab of the Options dialog box

useful when the program is getting it's data from another copy of ATCS Monitor over the network. The option allows you to specify that the program should attempt to reconnect to the server every 60 seconds if the connection to the

server is lost.

1.1.3

01/24/99

Fixed bug which caused the toolbar setting (visible/hidden) to not be saved to the profile with other settings.

<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	Fixed bug that caused program to crash most of the time when using an RM100 decoder to capture data and "Analyze Signal" was used to look at the signal.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	Fixed bug that caused Capture To File to encounter an error for a user.

1.1.1

01/10/99

Made modification to Ham Comm-type data slicer support to also support Optolinx data slicers.

1.1.0

01/10/99

<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	Added support for Ham Comm-type data slicers as an ATCS data source using a driver written by beepman
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	Fixed minor bug that left selection in Active Terminals selected (greyed) when you right-clicked in the Messages window.

1.0.1

<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	Added the ability see the received and interpreted signal (signal with any masking applied, from which ATCS data bits are interpretted) graphically. See "Analyze Signal" menu item in the View menu.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	You can now create rules to display items in the Messages window in different colors. In the window where you specify the text that should be displayed in the "Type" column you can specify whether the entry added to the Messages window should be displayed in the Message window's default color or another color.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	Added a new options panel. The new panel contains an option that allows you to specify that ATCS Monitor should appear as an icon in the system tray (where the clock is) when minimized.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	Modified program so that the packet window is not updated while the program as minimized to reduce load on the system (data recieved is still stored in memory though). When the program is restored (from the minimized state) the MDT window is refreshed with data that was received while the program was minimized.
<img src="_themes/zero/zerbul1a.gif" width="15" height="15" hspace="13">	Changed association of the control-T shortcut key... it now toggles whether or not the toolbar is hidden.
