Mohammad,

If I had to guess, I'd be willing to bet that /etc/pcmcia/config.opts is
messed up.  By default, a PCMCIA serial device (Like your modem) tries
to install as ttyS1 or S2, depending on your laptop.  If you check
config.opts, make certain that you are not excluding irq 4, or 3. 
/dev/ttyS0, and ttyS2 share interrupt 4.  /dev/ttyS1, and ttyS3 share
interrupt 3.  (They have different i/o addresses.)

If you comment out the appropriate 'exclude' line in config.opts, and
issue "/etc/init.d/pcmcia restart" it should work.  That's the best
guess I can make with the information you've provided.

Alan
