18.5. A chat script for PAP/CHAP authenticated connections

If your ISP is using PAP/CHAP, then your chat script is much simpler. All your chat script needs to do is dial the telephone, wait for a connect and then let pppd handle the logging in!

#
# This is part 2 of the ppp-on script. It will perform the connection
# protocol for the desired connection.
