[newbie] Modem Insatallation - Help -

[Miguel Olmeta]

Hi !!
I just installed Mandrake 7.0. (This is my very first Linux
installation).
I have an internal modem: US Robotics 56K, ISA, COM3, IRQ 5 .  When I
try to connect with my ISP (using KPPP)  I receive the messages:
Modem Ready
Sorry, the modem doesn't respond
Can somebody  give me some tips.. Thanks.
Regards,
Miguel
