Driver for Linux of Latitude C600 modem

Hi.

 I have a Latitude C600 with de combo 3com modem & ethernet.

 The net work fine on Linux (Debian) but i don't find drivers for the modem.

  You have drivers for this modem, for Linux?

 or how to configure others drivers similars?

 what chipset uses this 3com modem?

 

Thanks a lot.
