Hey Justin-

A while back, I was thinking about doing the same kind of thing.  From your
research, you should have found out that PCMCIA is a bit of a misnomer for
the cards.  PCMCIA is the name of the organization that created the PC-Card
and Cardbus standards.  Since you are using an old "pcmcia" modem, chances
are it is the 16-bit pc card standard and not the 32-bit card bus standard.
That's a good thing as pc card is a much simpler standard.  I would suggest
looking into a book called "Inside PC Card" by Faisal Haque (ISBN:
0-7506-9747-4) as it covers both standards in great depth.  The Pc Card
standard is based heavily on the ISA bus (as the card bus standard is based
heavily on the PCI bus).

Subject: [EE]: PCMCIA modem connections


Hi All
I would like to use an old pcmcia modem I have to connect to a pic. The pic
will use the modem to dial a phone number. I have this already working with
a normal serial modem but would prefer to use the pc card because of its
size.

Does anyone know what pin numbers to use on the card or how to communicate
with the card at all? I have done a small search and come up with some
standards that are gobblygook to me.

Any ideas?

Thanks
Justin.
