Usage: pon [OPTIONS] [provider] [arguments]
-q|--quick pppd hangs up after all ip-up scripts are run
If pon is invoked without arguments, /etc/ppp/ppp_on_boot file will be
run, presuming it exists and is executable. Otherwise, a PPP connection
will be started using settings from /etc/ppp/peers/provider.
If you specify one argument, a PPP connection will be started using
settings from the appropriate file in the /etc/ppp/peers/ directory, and
any additional arguments supplied will be passed as extra arguments to
pppd.
