Re: Error setting up dialup in Ubuntu 10.10 kernel 2.6.35.22

Hi Antonio

This is the terminal listing after following your instructions
immediately after boot:

derek@derek-desktop:~$ sudo ls /dev/ttySM0
/dev/ttySM0
derek@derek-desktop:~$ sudo wvdial
--> WvDial: Internet dialer version 1.60
--> Cannot open /dev/ttySM0: No such file or directory
--> Cannot open /dev/ttySM0: No such file or directory
--> Cannot open /dev/ttySM0: No such file or directory
derek@derek-desktop:~$

Regards  Derek
