Hi all
Does anyone know, or can point me in a good direction, on
what pins of a pcmcia modem are the serial in/out, rts, cd, dtr etc?
Thanks
Justin

Hey, I have a related question.

Is there a PCMCIA cell modem for use in the USA?  I need to have installers
use a cell connection without losing the cell voice contact.

RTS, TxD etc are NOT on a PCMCIA serial modem. The PCMCIA modem is a
PCMCIA device which attaches to the PCMCIA bus. The PCMCIA programming
specs are available and programming examples etc are all over everywhere,
including in good books (I can't quote a title now, sorry).

imho making a PIC talk directly to a PCMCIA device is a little too much
for the PIC.

hope this helps,

Peter

Sorry, but it's not quite that easy.  In the case of a 'generic'
PCMCIA modem, the PCMCIA port is a bus interface that looks like that
of a serial card of the type used in PCs. When you plug it into a PC,
the PCMCIA card gets mapped into I/O space at the normal serial port
address, so software can use it as if it were a conventional modem on
a normal serial port.
Within the card, there is also some memory which is used for card
identification & a little bit of address decoding, but most of this
can be ignored for your purpose. It wouldn't be too hard to interface
to - you'd need enough I/O for an 8 bit data bus & a few control lines
- most of the PCMCIA address lines could be tied high/low as required.
The official PCMCIA card spec tells you all you need to know, but it's
very expensive. An alternative is the book 'PCMCIA System
Architecture' (Addison Wesley ISBN 0-201-40991-7), which should cover
enough to interface to a modem card.
You'll also need data on programming the PC-style UART chips - try the
Nat. Semi. website.
