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-Tfollowed 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.
