install modem on mandrake linux

I am a new user in Linux. Just yesterday I quitted Microsoft and transferred to linux without knowing anything about it. I installed Mandrake linux10 . It completed successfully. But i Could not figure out what in the world I should do in order to connect to internet? I have dial-up internt connection and my modem is PCtel. should i install the modem ? If yes , how? If no.. what is the right way to configure internet properties. I tried KPP but it says..modem doesnot respond.

So please help me......I am desparately trying to use linux.. and internet is the thing i can't live without. If I could not solve it in a couple of days i should return back to microsoft again...

 

Is it an internal or external modem? Was it connected when you installed Mandriva?

 

internal

mine is internal modem...and it was working properly with windows

 

It's possible it's a Windows-only modem, i.e., there are no Linux drivers for that modem.
