# suid root (chmod 4744 [or something like that]), along with the other

# A really good suggestion for X-Windows users is to divert the output for
# this command to /dev/console using the tail command:
# tail -f /var/log/mesages > /dev/console
# This way you have something to look at in case things don't go right.
#
# You're obviously going to fix this file for your own username, password,
# modem speed, and other stuff.

# Script to initiate a ppp connection. This is the first part of the
# pair of scripts. This is not a secure pair of scripts as the codes
# are visible with the 'ps' command. However, it is simple.
#
# The proper syntax is now: ppp-on xxx-xxx-xxxx
# where "xxx-xxx-xxxx" is the phone number with area code.
# If no paramaters are entered, the script falls back to a default
# phone number. This case statement below also gives a usage and
# allows the user to dial an alternate phone number.
# This script will ignore everything after the first parameter.
