i don't know what else was in the machine referred to in the original
question, but in my experience, most machines that have pcmcia
capability are laptops (how i wish that were not true...).  many of
the "newer" laptops lack built-in serial rs-232 ports -- preferring
usb.  i've never seen a laptop w/ 2 built-in serial rs-232 ports (not
saying there aren't any, just not that many).

that said, for reference, one of the machines i'm using has no
built-in serial rs-232 ports and a pcmcia modem often comes up as
/dev/ttyS0.  iirc, this can change depending on what's plugged into
the various pcmcia slots.

in my /var/log/daemon.log, i see lines like:

  executing: './serial start ttyS0'

so looking there might give some clues...

just my $.02 ;-)
