Well, friends, this is getting a bit too complicated for me. The modem works on Windows Vista, set at 115200, using a simple phone line. wvdial configured the modem at 460800, saying: 'Max speed is 460800; that should be safe'. As far as I can tell my /etc/wvdial.conf (see below) is properly set up. I use the same phone number, username and password as on Windows. I've tried other speed settings (including 57600 - see below) and still get 'Authorization failed'. So, I wonder, of course, what to do next and I'd be grateful for any further advice.
