You may have to set up the serial port for it to work.
the commands 
stty /dev/<modem-device>
and
setserial /dev/<modem-device>
are the ones to use, particularly the latter.

man stty and man setserial are your friends.

That could well be the case.
Have a look in the lock files directory with the command:-
# ls -lRa /var/lock/

If there is a spurious lock file just delete it, and try again.
