Hey Martin:

I use a pcmcia serial card.  It looks like a standard serial port with the old io ports and irq's.  I've had it since shortly after
I left O.S.u.  Guess that was over 10 years now.  It still works though.  I'd think one could still get one.  If you are
interested, I can get the make and model.
