wvdialconf - build a configuration file forwvdial(1)
DESCRIPTIONwvdialconf detects your modem, its maximum baud rate, and a good initialization string and generates or updates the wvdial(1) configuration file based on this information.
wvdialconf is completely non-interactive. You still need to edit /etc/wvdial.conf to specify the phone number, login name, and password of your internet account in order for wvdial(1) to work.
It is safe to run wvdialconf if a configuration file already exists. In that case, only the Modem, Baud, Init, and Init2 options are changed in the [Dialer Defaults] section, and only if autodetection is successful.
