TAP initially known as Motorola Page Entry (PET) was adopted
in September of 1988, by PCIA or the Personal Communication
Industry Assosication (at the time known as Telelocator).
TAP defines the wireless standard for sending alphanumeric
messages to pagers.
The TAP/IXO Alphanumeric Entry Protocol is the industry standard
protocol for the inputting of paging requests to terminals.
Since the inception of TAP, the system and reciever capabilities
have expanded dramatically and new telecommunications protocols
have been introduced.
The standard TAP protocol supports ASCII with XOn, XOff in
either direction using a 10 bit code (1 start, 7 data, even
parity, 1 stop).
The following steps are the TAP standard. All paging terminals
and sending

steps:
