[En-Nut-Discussion] Virtual COM ports for PC's, emulating TCPIP or better yet, source code

[Nic Cave-Lynch]

Hi

Under Linux, you can do it with the pseudo tty arrangements. I've got 
some code but I'm afraid it's proprietary :-(

I'm fairly sure there are examples on the net. One possible is 
http://www.net-track.ch/opensource/retty/. Another that looks likely is
http://www.dest-unreach.org/socat/doc/socat.html

For windows: I know they exist, but I don't know about open source versions

Good luck

Nic
