Problem: I have several Unix workstations and two laser printers. I'm short
of serial ports on the workstations, but I have an AT compatible which is
nearly unused. The workstations and the AT are all connected via Ethernet. 
So I want to hook the printers on the AT. I need a piece
of software, which listens on the remote printer port and shuffles any
incoming data from the workstations to the printers.

Questions: Does such a program exist? (I'm sure I can do it myself. But if
a solution already exists I will find me a better way to waste
my time :-).
If the answer is "yes". How much does it cost? (e.g. is it cheaper
than buying a terminal server?)
If the answer is "do it yourself". Should I use MS-DOS or Minix?
If the answer is "use MS-DOS". I do not know very much about the
internals of MS-DOS. Which is the best way to serve a network
port and two printer ports in parallel in a single tasking system?
If the answer is "use Minix". Is there a TCP/IP package for
Minix? (ka9q?)
			 
Can someone please help?
