In Mode of Operation 4, all messages from a single peripheral port are
sent to the host port automatically. The host device may receive all
complete messages in the buffer of a selected port by sending the port
select code ($SELECT default) followed by ASCII capital S, the desired
port number (02 to 24), and a terminating character (0A Hex - Carriage
Return or 0D Hex - Line Feed ).
NOTE: The host device may select and transmit data to any peripheral
port while simultaneously receiving all messages from a single port.

In Mode of Operation 5, a single message is sent to the host port from
a selected peripheral port upon request. The host device may receive
one complete message from a selected peripheral port by sending the
port select code ($SELECT default) followed by ASCII capital S, the
desired port number (02 to 24), and a terminating character (0A Hex -
Carriage Return or 0D Hex Line Feed ). If there are no messages for
the selected peripheral port, 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 a single port.
