ports to another pc.

Using Unix OS's on both PC's this is easy, and I have done it to drive
serial devices in exactly the way you describe.

Under Unix serial devices are not treated differently to virtual pty's.
On the end connected to the device I ran a process from inetd that
connected incoming socket connections to the physical serial port. On
the other pc I spawned a process that connected a pty to the remote PC
on that socket, and told the application to use that pty instead of a
local serial port.

Search freshmeat as there are some examples of this... but if I recall
correctly I ended up rolling my own scripts.
