# This script monitors a comm port for any signals sent in (eg. cts, dsr)
# If detected, it dials a pager through the other comm port via a modem and
# sends 999, when clear it sends 666.
# I use it with a relay across pins 7 & 8 (RTS & CTS). The relay is triggered
# by the 12 volts from my burglar alarm (Most burglar alarms have a 12 volt
# hold off voltage which goes to the external bellbox, when the alarm is
# triggered, this drops.)
#
# Make sure you have the following UUCP files in place for CU to work..
# For Linux you should find sample scripts.
# cp /usr/doc/uucp-1.06.1/sample/* /etc/uucp/
# /etc/uucp/port : ( device = /dev/ttyS1)
# /etc/uucp/dial : ( check the dial string in case the modem is in quiet mode)
