Revision #: 1715
Enhancements:
- telmc column formatting improved to work in both 80 column and larger 132 column consoles.
Shows connected state in a column labeled "S" meaning state with one character: C means connected. R means awaiting reconnect.
- Beeping is eliminated in the server side. Rather Control-G character is captured and sent to the client side for the client to beep.
System beep call was already handled properly in previous release to beep in the client and not the server, so continues to work properly.
- View Session new advanced architecture now allows TelnetSSL and SSH sessions to be viewed as well as Telnet sessions.
- Install adds Windows firewall enabling entries so that Pragma Inetd and Cmdserver can open needed TCP ports for connections. Before this,
one had to manually add the entries in the Windows Firewall after install. For Non Windows firewall, one still has to do it manually.
Fixes:
- Session count is reduced properly before a session goes to waiting reconnect state. This allows a new session to come in
and reconnect. Limiting session to 1 also would work for reconnect which was failing before this fix.
- Servers with Pragma telnet server installed were sometime rebooting itself spontaneously as CcmdServer.exe process terminated the csrss.exe
process during shell process cleanup.

Revision #: 1055
Enhancements:

Release Date 07/15/09
Revision # 332
Enhancements:
- New Pragma Gen2 architecture for higher speed, reliability and enterprise
deployment readiness.

- Customer Application has clean documented way to send custom code for beep or special functions.
Pragma telnetd and sshd can work with the same custom code written by customers
- User drive letter mapping improvements to get logon prompts quickly by launching an extra
thread that maps user drives in the background; this thread exits when done. ThreadDriveMap
can be set to "no" to avoid this asynchronous drive mapping for scripts who may need drive letters
at the launch
- Windows PowerShell is now fully supported and can be set as the default shell
- Supports new Windows Server 2008 R2 and Windows 7
- All languages supported by Windows are now supported by sshd server and clients.
UTF-8 (65001) is a good page to choose. Users can choose any CodePage and Fonts that support their national language.
Fixes:
- Group access not detected correctly
- Client disconnects at any time will not tie up telnet server
- Fix for orphan sessions not cleaning up requiring reboot of server
- If "PATH" in user level was set, it would override "PATH" in system level. Now User level PATH is appended after system's PATH.
Clients/Tools:
- telnetc supports TelnetSSL protocol. telnetc /s option is used to invoke SSL.
FortressCL
- control-c and control-break is now passed to server enabling application termination/exit.
