v2.5.9

• Using the Application Compatibility Toolkit found that IP-Com should be opening "\\\\.\\COMx" instead of "COMx".

v2.5.8

• When using prevent system standby ability, check that the OS has this functionality by using LoadLibrary rather than looking at OS version. This enables the program to run on NT4 with Internet Explorer 4 installed.

v2.4.1

• Added Help.

• Removed need for a thread per remote client. Now only one socket server thread.

v2.3.1

• Fixed major buffer overrun bug when in telnet mode. 

v2.3.0

• Removed use of CAsyncSocket over multiple threads. The CAsyncSocket class is broken when used by more than one thread. Now using a thread that is triggered to read the socket..

v2.2.2

• Logging improvements.

v2.2.1

• Support Reception of 'Are You There' telnet commands; respond with "YES".
• Fixed logging of multiple telnet client disconnections.

v2.2.0

• Optional support for telnet protocol from clients. Telnet protocol characters will be stripped before being sent to the COM port. If not selected then IP->Com will operate in RAW mode.
• Allow IP->Com to inform telnet client whether equipment connected to the COM port will echo received characters.
• Support telnet 'are you there' command to detect crashed telnet clients. Timeout set to 2 minutes of inactivity.
• Support for optionally stripping line feeds received from n/w client.
• Added current time to log items.

v2.1.9

• Enable keep alive on sockets. If client crashes, then after some time (usually 2 hours), IP->Com will enable server socket again.
• Default address now blank, to signify all available i/f's.
• If listening on server socket fails, then delete socket etc. This can occur if an i/f is disabled after a client has connected.

v2.1.8

v2.1.2

• Error handling tidy up.

v2.1.1

• Fixed lockup problem when closing program with large data throuput.
• only allow first telnet client setting now the default.
• Rx worker threads now set to THREAD_PRIORITY_ABOVE_NORMAL priority.

v2.0.0

• Allow multiple telnet clients to connect, optional per COM port.

v1.4.0

• Changed name to IP->Com. Should have done this a long time ago!

• Running under NT would give COM1-COM32, ignoring the registry, now fixed.
• Fixed possible memory leak, under low memory conditions.

v 1.3.2

• Still wasn't picking out ports on internal modem cards. Therefore used regmon (Systems Internals) to discover what registry keys hyperterminal queries. Now decided that on WinNT and above IP->Comm will also read the  hkey_local_machine\hardware\devicemap\serialcomm key for ports. This should now behave in the same way as Hyperterminal (or better).

v 1.3.1

• Registry key match relaxed even further! Now uses 'portname' key to identify COM ports. I wish Microsoft could have made this easier.

v 1.3.0

• On Windows 2000 and above, serial port expansion cards would not be detected due to different registry key to standard ports, search now relaxed (thanks to Johan Wallin for reporting this).

v 1.2.9

• Wait cursor now implemented when pressing disable button.
• Added hyperlink in About box.
• Installer now uses Inno Setup.

v 1.2.8
