NOTE: Standard units support Remote Diagnostics mode only.
Diagnostics mode allows the active terminal to perform various tests
with a remote Telplex unit if a communication link is established.
Multi-drop units also allow the same tests to be performed on the local
unit. The active terminal may communicate individually with any port
on a remote Telplex or the local unit (multi-drop units only) or perform
a self test on all ports.
The full duplex diagnostic tests a selected port's ability to transmit and
receive data. Any data received by the active terminal port will be
transmitted out the selected port and vice versa. The loopback
diagnostic allows the active terminal to have all data typed on the
keyboard echoed back to the terminal screen by the selected port.
The self test diagnostic checks various internal components for all
ports on the Telplex.
Section 4.3.4.1 describes Local Unit and Remote Unit Diagnostics
mode for multi-drop units and Section 4.3.4.2 describes Remote Unit
Diagnostics mode for standard units.
