The
Operational Modes
available for paging using the
TAP Paging Protocol
include:
System Identification Command
Paging Session Login
Paging Operation
Paging Session Logout
SYSTEM IDENTIFICATION COMMAND
The System Identification command allows installation programs and other software applications to poll serial ports for the
existence of a
WaveWare v
8
Paging Encoder
using the Standard
ATI
Command. This can be used for a supervised
process (also called keep-alive) where the host system periodically polls the paging system for a response. When the
WaveWare paging transmitter recognizes a command formatted as
ATI<CR>
, the transmitter responds with the following
message:
WaveWare Paging Encoder v8.00<CR>
(The firmware version number is subject to change)
PAGING SESSION LOGIN
The
v
8
Paging Session Login
mode allows a
Host Device
, sometimes called a Remote Entry Device, to initiate
communications with the paging system. With the
WaveWare v
8
Paging System
, the Login process is optional. The
WaveWare v
8
Paging System
will automatically login a Host Device and process the paging message if it recognizes a
properly formatted TAP message block at any point in its operation.
The
Host Device
initiates the Login process by transmitting a carriage return
<CR>
character every two seconds until the
paging system properly responds or until the Host Device times out and notifies the operator of a bad connection. The
paging system will respond with
“ID=<CR>”
(Note: the quotation characters are used here only for reference and are not
included in the transactions). The
“ID=<CR>”
will not be repeated or timed out by the paging system.
The
Host Device
should respond to the paging system with:
<ESC>PG1<CR>
or
<ESC>pg1<CR>
The
WaveWare v
8
Paging System
will then respond with:
110 1.8<CR>WaveWare Paging Encoder v7.29<CR><ACK><CR>
The
“110 1.8”
message indicates that the system conforms to
TAP
specification
version 1.8
and should be backward
compatible with earlier
TAP
implementations. The paging system then notifies the Host Device that it is ready to accept
messages as follows:
<ESC>[p<CR>
This completes the Login process.
