I have given up trying all tricks to use the internal modem of my toshiba laptop to connect to the world. Seems to be not possible.
Ok Then I bought an external modem which exist nowadays only in the USB version unfortunately, could not find a serial one any more.
However while this modem works well under windows, it is simply ignored by linux. When I try to contact the modem, I am getting only some error msg not able to open modem. simply no reaction of the modem at all.

Tried on 3.6 and 3.7, both versions on my laptop installed, treid it from user and from root, nothing.

Can anybody tell me how to connect to internet by knoppix appart from full network connetcion?
