Dan, Thanks for the gnome-ppp front end to wvdial. But could you relate how the Gnome-ppp -> Setup -> Options -> Check Carrier Line actually works? This is important to those using the slmodemd helper application, in service with the ALSA modem drivers and the Smartlink slamr and slusb drivers. Each of these drivers + slmodemd act through creation of supporting symbolic link: /dev/ttySL0 --> /dev/pts/N The /dev/pts/N ports are not yet Sound supporting, so it is obligatory to use in /etc/wvdial.conf a line Carrier Check = no When I uncheck the gnome-ppp Option "Check Carrier Line" There is no change in the gnome-ppp config file /home/UserName/.wvdial.conf Could you please explain what and how this check off acts.
