If you do "cat /proc/tty/driver/serial", what do you see? Among the 
values listed, can you eliminate any as belonging to a known device? 
Typically, the modem will belong to a ttyS# with number between 0 and 3. 
The number 0-3 will correspond to a combination of the irq and port. The 
common base addresses are 0x3f8 or 0x2f8, in combination with irq 3 or 
4. [together there is a possibility for 4 tty's within that range]

Or, to make life simple, you probably have a /dev/mouse, and if it is 
not a PSAUX or USB mouse, then it will point to one of the ttyS devices 
that you can eliminate. You can then manually do trial and error for the 
remaining values of ttyS0 through ttyS3 (COM1-4).
