Except if you modem is a winmodem, it should answer to the Hayes command set. Take a look at : Hayes command set - Wikipedia, the free encyclopedia
connect to modem with 'minicom' (usualy include in all distro (need to be installed by your package manager. e.g. urpmi minicom / yum install minicom /...)
Try the 'AT' command follow by CR. It should anwser 'OK'
Then the command you need are ATI0 to ATI9 this give you lot of information about your modem. (look at wikipedia link above).

I'm not sure that it would work, but you could also try connecting the modem and then running the dmiecode command to see if it provides any modem info. Checking the manual page for dmiecode will give you some options for using it.
