Just as a test, I'd try the following command:

echo ATDT(some_phone_number) > /dev/ttyS0

and see if you hear the modem pick up and dial. If you've got a second phone
line (or cell phone, etc), you can dial it and answer it and hear yourself
talking to yourself (if you've got a speaker on the modem).

echo ATH > /dev/ttyS0 to hang up the line.
echo ATZ > /dev/ttyS0 to reset the modem.

If this test works, it'll verify that Linux and your modem will work together,
and that the hardware is okay.
