#!/usr/bin/expect -f
#
# This script was written by Jim Isaacson <jcisaac@crl.com>. It is
# designed to work as a script to use the SecureCARD(tm) device. This
# little device is mated with a central controller. The number displayed
# on this card changes every so often and you need to enter the number
# along with your user account name in order to gain access. Since chat
# is based upon fixed strings this procedure will not work with chat.
#
# It is included by permission. An excellent reference for the expect
# program used by this script is in the book:
#
# "Exploring Expect"
# by Don Libes
# Published by O'Rielly and Associates
#
send_user "hello, starting ppp\n"
system "stty 19200 -echoe -echo raw < /dev/ttyS3 > /dev/ttyS3"
