NOTE: For illustration purposes, the factory default control character
(
Control-T ) will be used in the following descriptions of the Modes of
Operation. Section 5.2 provides more detail for operating in the
various modes.


 
 


Mode of Operation 1 increases input/output by interfacing a single
port on a computer with full duplex communication to four, eight, or
seventeen peripheral devices. The communication is full duplex
between the host device and the selected peripheral device. For the
host device to select a specific peripheral port, it would send
Control-T
followed by the desired peripheral port number. The host remains
connected to the selected peripheral port until another peripheral port
is selected.
NOTE: Peripheral port selection is done in the manner described
above for all Modes of Operation.
Factory default is Mode 1 with the host port connected to Port 2
on power-up.

  
 

Mode of Operation 2 provides multiplexing to the host port of all
messages from all peripheral ports automatically. Data is buffered
until an end of message terminating character is received or until the
buffer is full. The messages are sent to the host device preceded by
a port identification number corresponding to the port number of the
peripheral device that actually sent the message.
