Thanks to all those that responded... to my earlier query regarding
multi-port serial cards.

I've found what looks like a local supplier of the TC-400 card
mentioned here recently though I've not yet checked prices.  Stallion
and digiboard looked way too expensive - they seem just as expensive
as they were 5 yrs ago...

Now for the followup question.  Is there any reason to get a PCI
version of the card as oposed to an ISA card?  I'm guessing that for
serial comms the ISA bus is ok, so prefer not to use up a PCI slot.
An ISA card can also go into my old i486 if need be.

Thanks
