The Telplex will also send an XOFF character out of a local terminal
port if the transmit buffer of the designated remote terminal port fills.

When the Telplex transmits data to a terminal device and the terminal
device cannot receive any more data, the unit will expect to receive an
XOFF character. When the terminal device can receive more data,
the Telplex will expect to receive an XON character.
If a terminal port on the local unit receives an XOFF character, the
transmit buffer for that port will begin to fill. If the transmit buffer fills,
the local unit will signal the remote Telplex to handshake the
designated remote terminal port.

The programmable features of the Telplex may be accessed from any
terminal port which has Local Access enabled (see Section 4.1.2.3 ).
From the factory, Port 1 is the only terminal port that has Local
Access enabled. You may also program the terminal port features for
a remote Telplex by accessing Remote Unit Configuration mode.
User-programmable features for the terminal ports include serial port
configuration (i.e., baud rate, word size, etc.), Block Size, and Status
Messages. Serial Port Destination and Unit Number are
programmable for multi-drop units only. User-programmable features
for the composite port includes baud rate, Line Type, Clock Type, and
Programmable Strings.
The procedure for configuring multi-drop units and standard units is
basically the same. However, the resulting configuration menus are
different in appearance. These differences will be specified in the
following sections. The menus shown will be for the TX104 which are
similar for the TX102 and TX108.
