Another person on this forum (different thread) said that my modem is a winmodem so it seems I will not be able to get my modem to work. Thanks for the help, eon and jjmac.

I am suprise that my modem is a winmodem. When I bought my pc, there was nothing mention about the modem being a winmodem. In windows, I look at my modem and there is no mention about the modem being a winmodem.

In control panel when I click on my modem and look at the property I get this:

Port: COM 2
Interrupt: 3
Address 2f8
Uart INS 8250
Highest Speed:115 Baud

ATI6 DP Rev BA

I wan to thank everyone for the helping me.
