You do not "see" a modem. It does not require a module/driver. If you
are able to use your communication port(s) on your computer, that's
it. The rest is configuration of a userspace dialing program.

You should focus on getting your com ports functional (if not). If
there is no problem on your com ports, you won't have a problem
"see"ing your modem.
