According to Mac OS X, this is the modem in my powerbook:

   Driver:      MotorolaSM56K.kext (v1.2.0)
   Hardware Version:    Version 1.0
   Interface Type:      I2S
   Country:     B5 (United States, Latin America)
   Modem Model: Jump
   Modulation:  V.92

Do you know if that's a Conexant HCF modem, or something else?
Is linuxant.com the only place to get HCF drivers?

Thanks, Bruce.
