TELEPHONE=972-2800
#TELEPHONE=219-9655

ACCOUNT=username	 # The account name for logon (as in 'George Burns')
PASSWORD=userpasswd	 # The password for this account (and 'Gracie Allen')
LOCAL_IP=0.0.0.0	 # Local IP address if known. Dynamic = 0.0.0.0
REMOTE_IP=192.108.254.11 # Remote IP address if desired. Normally 0.0.0.0

# This is the location of the script which dials the phone and logs

  # forget the 'lock' option or some programs such as mgetty will not
  # work. The asyncmap and escape will permit the PPP link to work with
  # a telnet or rlogin connection. You are welcome to make any changes
  # as desired. Don't use the 'defaultroute' option if you currently
  # have a default route to an ethernet gateway.
