Mode of Operation 3 provides message multiplexing to the host port of single messages from all peripheral ports upon request from the host device. A single message from all ports is sent to the host device only when a command is received from the host device. The request for messages command is the control character (Control-Tdefault) followed by ASCII capital S. If there are no messages, the host port will send a Line Feed character to the host device.

NOTE: The host device may select and transmit data to any peripheral port while simultaneously receiving single messages from all peripheral ports.

In Mode of Operation 4, all messages are sent to the host port from a selected peripheral port. The host device may receive all complete messages in the buffer of a selected port by sending the control character followed by ASCII capital S and the desired port number (1 to 4 for the 525H, 1 to 8 for the 528H and 529H, and 01 to 17 for the 5218H).

NOTE: The host device may select and transmit data to any peripheral port while simultaneously receiving all messages from a specific peripheral port.
