# Logical "Pager Machines" which stand for paging codes
#
#    These are the pager calling codes, with a distinct
#    "machine" for each calling code. After dialing the
#    pager number, five one-second delays are placed in
#    order to allow time for the pager service to pick up
#    the phone.  This may change based on how long it takes
#    a particular pager service to pick up the phone.  The
#    code is sent once followed by a standard termination,
#    and then one more time, after a pause, just in case
#    the pager service was not ready the first
#    time the code was dialed.

# 1 - In actuality, only the first seven digits are recognized
#     uniquely to identify a target.  Keep this in mind when
#     making up your own names.
#
# 2 - In my experience, I found reliability to degrade when
#     I used more than 23 digits in the dial sequence.
