should be no problem at all, hook the modem up to a serial port, know which one you hooked it up to. If com 1 this will be /dev/ttyS0 in a linux system, com 2 will be /dev/ttyS1.
Now lets make sure it is enabled in the BIOS, many BIOS may have this disabled.
Boot into linux and lets see if we can query the modem - open the application minicom in a terminal (xterm, Eterm. konsole...). It may need to be set up so so this as user root. Set up should be self explanitory. Issue an command - ATZ should return something like an OK.
let us know how it goes.
