Hi,
I've a Mandriva 2007.0 linux distro with KDE.
I've an external serial modem (a TRUST 56K V92);
this modem worked fine until this morning;
practically, by mistake, I've removed "modem parameters/configuration" in the KPPP configuration window;

So, after that, I've created again the "modem configuration";
I've saved all, and I've interrogated the modem;
It answers correctly.

But when I try to connect to the internet, it stops at "modem initialization ..." stage until I kill the process.

I've noticed, that the SD led of my modem, that is the led pointing out, when data are sended (SD = Send Data), switchs on and remains on, when I click on the connect button of Kppp.
This isn't the correct behaviour, because If I try to connect with the same modem under Windows XP, it connects fine, and the SD led is off.

I've tried to reinstall ppp daemon and Kppp, but nothing changed.

What's happened?
What this can be due to?

Thank you in advance.

You said it yourself: you've misconfigured kppp.See?

... the configuration file remains after the removal and is unchanged by the reinstall.

Probably the initialization string is bad.

Thank you for the answer Simon,
effectively, all AT commands in the Kppp configuration window (that is all the AT commands in the configuration file /home/muysername/.kde/share/config/kppprc) are disappeared;

but why this?
It can be due to the fact I've reinstalled kppp?

Anyway, where can I recover these commands?

Thank you in advance.

Ok,
I've solved;
pracatically, I've uninstalled kppp 2.4.4 and reinstalled Kppp 2.4.3;
init AT commands are so reappared.

Thank you very much Simon!

Bye

There should be some way to enter your own initialization string.
If you look in that booklet that came with the modem, the manufacturer will have suggestions.
