HP Omnibook Modem problem

[Brandy]

I have a HP Omnibook 2100 running Win98SE that uses a Xircom CEM56 modem to access the internet, this modem will dial and make a number ring, ex. my home phone, but it never completes a connection to my service provider, I get a message that the server did not answer, although I can hear the usual noises that are made after the ringing to the service provider until it times out and gives me a message that the ISP did not respond and to try later.  I have tried drivers from just about every source I can find but no solution.
I am hoping someone here can help.

Thanks
Brandy

I would try that modem card in another notebook to see if it is faulty...

How old is it ? ?
