There are a number of companies that manufacture multi-port systems
for PC's, a number of which have dos drivers which provide virtual
ports above com4. Try contacting Consensys in Toronto (they make a 
board they call PowerPorts) or your local DIGIPORT dealer (Your local
Novell office may be your best bet for Digiport info). I beleive
both companies have DOS drivers for thier boards. I know that AT&T
used to make a board called the IPC-802 which could be set up to
run under DOS with the right drivers. I'm not sure if the IPC-1600
has equivalent drivers, though.

Good luck!
