The Port Destination for individual ports on the Model 24 may be
configured as computer or printer. Computers and modems connect to
computer ports. Printers and plotters connect to printer ports.
A minimum of one port must always be assigned as a computer port
and at least one port must be a printer port. It is suggested that Port 1,
the master configuration port, be designated as a computer port to
allow easy access to all features of the configuration mode. The
remaining ports may be configured as computer ports or printer ports in
any combination and in any order. The Model 24 automatically
converts data from serial-to-parallel and parallel-to-serial. However, if
computer-to-computer communication is required, the computers must
be connected to serial ports to allow full duplex communication.
Factory default configuration is Port 1 (serial) a computer port,
Port 2 (serial) a printer port, and all remaining ports (serial and/or
parallel) computer ports.

To select a port in multiple peripheral applications or when
computer-to-computer communication is desired, the computer sends
the Port Select Code (which consists of any ASCII character string
numbering from one to eight characters) followed by the desired port
number and a terminating character: Enter/Return or Line Feed .
The Port Select Code is trapped by the Model 24 if it is valid and not
passed to the peripheral or computer. This code may be sent by
physically inserting it into a file. Alternatively, BayTech's memory
resident port select program will automatically send it for you by striking
hot keys or using a mouse.
