There is a book called 'PCMCIA System architecture' or similar which has =
most of the info in it.=20
Talking to I/O cards is not in principle particularly difficult, but =
getting the hardware info may
be. Things like modems typically emulate a standard PC-style UART, and so=
 ought to be pretty easy to
figure out - GPS cards may also use a similar interface.

It may be worh hacking around with the card on a PC to see if you can =
figure out the interface - the
card will usually be mapped into PC I/O space when inserted.=20
