IRQ 5 ought to be OK, though it seems to be everyone's first choice for an
"open" IRQ.  The Hostess cards I used for my NBC project used the address
space 0280h-02bfh for an 8-port card.  With the normal 2 serial ports in the
PC, that was a total of 10 serial ports.

Ah.  If you wanna telnet into the box, then forget I said anything about
Crosstalk.  I had imagined your wanting to sit at its console and see the
serial ports on several other machines.
