Can you run the "Modem query" in kppp successfully?

If not, can you run pppconfig, and use the command ppp-go -c (or ppp-on) in an X terminal? pppconfig is available from Debian at http://www.debian.org.

Before trying to connect anywhere, you should check if the communication with the modem is ok. For that, run:

 minicom -s /dev/modem

 as root and see if you can query the modem with a few AT commands. Once this step is cool, we may proceed.

 Also make sure you're setting the speed for your modem port at startup, like putting a line in /etc/rc.d/rc.serial that would look like:

 setserial /dev/modem spd_vhi

 This sets the port to 115200bps, needed for high speed modems, 28800 and higher.

 Good luck!

Yes i query the modem successfully with kppp i write AT and initialize the modem but when i try to dial something it says "No dialtone" although that i can hear the dialtone from the modem. I think that i should make the dial programm not to wait for dialtone and to start dialing as soon as i hear the dialtone from it.

To do so you just add the "X3" command to your modem string. This way it will dial out as soon as it pick up the line without waiting for the dial tone. This may cause it to fail sometimes, so you'll probably want to add some "," before the number to be dialed out. It makes the modem wait for a while before dialing, thus avoiding the fail.
