I usually use something like

#!/bin/bash
if ! ping -qc1 $rem_ip >& /dev/null
then
  /usr/local/sbin/DialWasp
fi

although my current ChkModem script is just under 100 lines of Perl :)
It makes sure that if there is a problem dialing up, it will not cost the
customer a fortune in calls by redialing every minute
