Modem doesn't do anything

When I try to connect to the Internet with the connection Wizard, at
says “Initialising Modem” - but the Modem doesn’t do anything (one light
shortly flashes) and then it says “Failed”. I tried another COM-Port and
also changed the Innit-String, but no success yet. :frowning:

It is an USR 33.6 Sportster Voice Modem.
