My laptop has a built-in serial port, so the modem is assigned to ttyS1.
In my original post I also forgot to mention that I am running kernel
2.2.15 and pcmcia-cs 3.1.8. I find out in the Debian Bug track system that
there is a bug in the serial.o module in the kernel whcih causes it to
mess the address in serial PCMCIA devices. This is why the modem could not
be opened. Newer versionr of PCMCIA (> 3.1.8) have a workaround for this
which consists in a few lines added to /etc/pcmcia/serial. Someone posted
a patch to the Bug tracking system. I've tried it and now everything works
