First, it definitely is possible although I've never used your particular
card. I've done it several times with several machines and my good old
Apple II on the other end. Things you didn't mention but might want to
consider are baud rate and word length (i.e. is the high bit set or not
this also has an effect on parity or what the machine thinks is parity. Also
stop bits can cause some problem). I would dump from the Apple to the IBM
first since I was always able to configure the IBM easier than the Apple
(I never really had a good transfer program for the Apple). Try low baud
rates at first and when you get something them put them where you want. Also
just dumping through the Apple as if through a printer port is a good
place to start.
