# Simple program to connect to:

# and send a page.

# This program still beta, but working better.
#
# Changelog:
# 10/21/99:  Modified original code and get paging to function.
# 10/22/99:  Fixed Error checking.  Checks PIN length, outputs failure message.
#
# REQUIRES MODULES:  strict and IO::Socket
#
# USAGE FROM COMMAND LINE:  echo "message" | example_pager.pl PAGER_PIN 
# Where PAGER_PIN is the PIN of the pager you want to send MESSAGE to.
#
# This program will send the page using 
# www.pagemart.com/cgi-bin/rbox/pglpage-cgi
# and will store the response in LASTRESPONSE.html when the server replies.
#
# If you are looking at this program for examples of code to make it work,
# check out the page{} subroutine below - it is the meat of this program.
