Hi Sam,

How was it jumpered when you got it? This is just a guess, but
could it be that pins 1 and 2 select com port 1 or 2 and pins 3,4,5
and 6 select the the IRQ, 4,3,5 or 2? Pins 1 and 2 could also be a
binary sort of thing that will select com 1 thru 4 depending on how
they are jumpered. None for com 1, 1 for com 2, 2 for com 3, both
for com 4.
