Sorry for this post guys but my modem is making me crazy. I have a laptop and my internal modem is an agere system AC97 modem. Now this f__king peripheral give me error 680 "no carrier". Now: The telephone cable is correctly cabled The telephone cable is working I have tried it in 4 different houses I have latest driver I have tested all functionality (ati*) with hyperterminal I have made all updates for my WinXp sp2 I have already tried to reinstall driver I have already tried to deactivate it and back I have already tried x3 init string I have set the right country I have tried with another country I have deactivated "wait for ring-tones" (if I try this the error is "no response from server) I have tried with ,,,, in front of the telephone number I can't hear anything from my speaker Madness. If there is some hardware-hacker-guru in this forum that can help me I will be very happy. Thanks in advance.

If it's responding to AT commands, I'd have thought it works - drivers aren't going to help it if you can get that far with it. Have you tried switching between pulse/tone dialing? Fire up a connection in hypertrm to the serial port it's connected to and try ATDT followed by another phone number (eg mobile phone) - if that fails, try ATPT followed by the number.
The only other thing I can really think of is damaged hardware - a broken track/dry joint on the phone socket.

Yes, I've tried all but nothing. I can't hear anything and hypertrm say no carrier. Can it be broken?

Sounds like it... if the drivers weren't working or it wasn't installed properly I wouldn't have thought it would respond to anything. Has it ever worked?

Yes ever. One day suddendly it starts to not respond. It was unplugged from the telephone line so I can't think of some electricity damage from the main line. I'm lost. If it is broken ati commands should not respond...

That's what I mean - it could be that the socket has (physically) broken, so whilst it responds to commands it cannot connect properly as it can't make an electrical connection to the phone line.
