TCP <--> Com port

Hello,

There is a commercial SW product called "TCP-Com" (http://
www.taltech.com/products/tcpcom.html ) which allows redirection of
RS232 communication ports to TCP/IP connections. One can access a
number of RS232 ports on a remote computer via TCP/IP connection to
that computer. It also allow creation of virtual RS232 ports so that
existing SW applications for RS232 can transparently use TCP/IP
connection.

QUESTION : Is there any open source, Linux version of TCP-Com like
application?

Regards,

Albert Goodwill

There's even an RFC for it.... But the name escapes me. It exists,
I've used it.

Google for telnet protocol over tcp or something similar - you should
hit on the RFC, and go from there.

One caveat:

There are linux servers and linux clients, GPL/OSS and free. The
Windows clients are $$$.

Ignore my previous reply, I thought you were looking for a hardware
solution.

Never tried it myself, but you might want to hunt down
the ser2net package or try something along the lines of

while(true); do netcat -l -p <port> -c "cat /dev/ttyS0"; done

These are some hints I picked up on Usenet for this type
of problem. As I said, I never tried them out myself.

HTH. YMMV.
