I think you'll have a more successful time if you jumper it to use a specific 
IRQ / comm port. Doublecheck your configuration - usually you'll have the 
modem on one IRQ/comm port and the mouse on another. If the mouse is already 
working on one IRQ, choose the other one :).

/dev/modem is usually a symbolic link to either /dev/ttyS0 or /dev/ttyS1, 
whichever your modem is on. If your modem is on 'com 1' (in windows/dos) then 
you should use /dev/ttyS0.

It's possible that /dev/ttyS1 is your mouse. It's busy :).

Like I said, the approach I would take first is to jumper the modem to use 
the 'other' comm port (most systems have two of these, although it is 
possible to have four total). You can try echoing characters to the modem 
device from the command line if you want to check if it's hooked up right. 
Alternatively try interfacing with the modem through 'minicom' which should 
be installed on your system. It's a terminal-based comm program which is 
pretty easy to use. At least you should be able to type out somehting like 
"ATDT xxxxxxx' to see if the modem dials.
