Just a friendly time saver tip, instead of dealing with
HAI encryption and login in BS, creat a message with a
simple string like "ARM" and "DISARM" then create a HAI
program that arms /disarms when it recieves that message
on the com port. then in RTI create a series of page flips
to simulate a pass code. so if the user code was "5832"
on the first page only the 5 key page flips you to the
correct next page, then on that page only the 8 key takes
you to the correct page, so on and so on, any other key
flips you to a dummy page. On the final page it gives
you the ar/ disarm buttons with a the proper message as
the 232 string.
