26
In Port Select Mode B (port selection at beginning of sending), the
Model 24 looks for the Port Select Code in the first 16 characters
received. If the first characters of the Port Select Code are not
received within 16 characters, the data will be routed to the previously
designated peripheral. If the first characters of the Port Select Code
are received within 16 characters and a valid port select sequence is
then received, the new port number is stored and data will be routed to
that peripheral.
The Port Select Code may be sent by manually inserting it into the file
or by using BayTech's support software to send it for you when you
strike the designated hot keys. Please see Section 6.2.8 for a
description of various methods used to select specific peripheral ports.

In multiple peripheral applications, if no specific peripheral is desired
(i.e., if the output may be sent to any peripheral), you may send the
port contention sequence which consists of the user-defined Port
Select Code (factory set is $SELECT) followed by "0" (zero) and a
terminating character: Enter/Return or Line Feed . The data is sent to
the buffer of the Model 24 and passed to the next available peripheral
on a first-in-first-out basis. The unit powers-up from the factory in
contention mode.
The port contention sequence is trapped if valid and not passed to the
peripheral. The Model 24 will send all print jobs received from the user
that sent the port contention sequence to the first available peripheral
until another port selection request is received.
If you have sent the port contention sequence and wish to select a
specific peripheral without changing the default (i.e., to select a port on
a one-time or temporary basis), send the Port Select Code, capital T,
the desired port number, and a terminating character. Subsequent
print jobs sent without a port select sequence will be routed to the first
available peripheral.
