I have this fictional scenario that I may try to play out to see if it works.

I want to relay a serial port from location A to location B.

Location A has a device that you would hook a terminal up to via serial port (IE: a smart switch that you would hook to your computer and use a terminal emulator to administer it).

Location B has a dumb terminal.

Using 2 Linux computers (1 at each end), I want to be able to administer that switch through the dumb terminal just as I had it hooked directly to the switch.

For the purposes of this discussion, assume that the systems can freely communicate via TCP/IP (such as over a VPN). Using a dumb terminal in Linux to ssh to the other linux box and then minicom to the serial port is not an option.

Basically, anything sent IN the serial port at Location A must come OUT the serial port at location B UNMODIFIED.

For now, there is no real practical situation I have in mind. It is more-or-less to broaden my knowlege of linux a little bit.

Would be cool if I had a computer here in the US that had a serial-serial connection to a linux PC, and dialed out on a 9600 baud modem in australia, as if it were directly connected to the american PC. Fairly pointless, but cool none the less.
