PCMCIA bus is _very_ similar to ISA bus.

You don't need too much at all to talk to a PCMCIA modem. Certainly not a
full-blown card and socket services. In the early days of PCMCIA many cards
came with a 'point enabler' which basically would turn on the card so that
it would appear, effectively, on the ISA bus. At that point you could talk
to it just like an ISA modem.
