I can confirm Doug's recommendation, as I have been using the byterunner cards
on several computers for a number of years.  I wanted to add, however, that
another option (if you are not limited in the number of ISA slots) is that you
might consider adding one of the 2-Com port cards w/ a couple of Parallel
ports.  Typically, you can select both IRQs and addresses on these cards for
each port.  I have not used any of their PCI cards, but the ISA cards do not
need drivers (based on my experience) for DOS, Win98, or Win XP.  Win 2000 does
seem to have a problem unfortunately getting COM 3 & 4 to share IRQs with COM 1
& 2 ,which I have not been able to figure out so I gave up on that OS for any
kind of logging.
