Do you need a real serial port involved at all? It sounds like what
you really want is a linux device that looks like a tty in terms of
accepting ioctl's from a program that thinks it is a serial port, but
actually accepts a tcp connection. I suppose you could rig a
loopback cable and actually have a separate program writing to the
serial port with the loopback returning it to your listening
application.
