SECTION 3 - BASIC OPERATION
IDLE
In the Idle state, the Paging Terminal is waiting for a request to connect.
The Terminal is not really idle because it is performing a number of jobs.
It is also monitoring the CRT port for user activity. It may also be
paging.
The Terminal is constantly monitoring its Paging Batches so that whenever
the batching period for one of them has expired, that Paging Batch will be
sent to the transmitter. This particular monitoring operation is the most
important job in the Terminal and continues at all times, whether the
Terminal is in the Idle state or actively interfacing over the computer
serial port.
A request to connect occurs when a CR (Carriage Return) key is input to the
computer serial port. CR is used to request Logon.
COMPUTER SERIAL I/O ANSWER
Once the Paging Terminal determines that it will be operating by data
transfer through the Computer Serial I/O port, it prints the inquiry "ID=".
The caller can then select which operating mode is wanted by typing the ID
character or character string and entering it with CR.
COMPUTER SERIAL DISCONNECT
The Paging Terminal will remain in the selected operating mode until the
Caller leaves that mode or until a timeout occurs. As for Line Disconnect,
the Computer Serial Disconnect is orderly and includes a good bye message
and a sum-check of the Programming memory values if exiting from
Programming mode.
The Caller can exit from the manually operated modes by typing a 'CR' at
the top level prompt. The automated modes terminate when the Paging
Terminal receives an 'EOT' character.
The Paging Terminal can be programmed to ignore timeouts when it is
operating via the Computer Serial port. The operator will not have to
repeat the Logon procedure each time the Terminal is left unattended.
COMPUTER ACCESS
Computer Serial I/O Connection: A CRT terminal or personal computer
equipped with a serial I/O port can attach directly to the Model 16. This
is the preferred access whenever the Operator Station can be located near
the site of the Paging Terminal.
