4.6.1.3 4.6.1.3 RTS/DSR PASS THROUGH RTS/DSR PASS THROUGH
If RTS/DSR pass through is enabled for a local terminal port on the
Telplex, the state of the RTS input line for this port will be reflected on the
DSR output line of the designated remote terminal port.
As an example, refer to Figure 1 on page 2. Suppose RTS/DSR pass
through for terminal Port 1 on both units is enabled. If Port 1 of Unit 1
receives a false condition (negative voltage) on the RTS line, Unit 1 will
signal Unit 2 to make the DSR line of Port 1 false.
If RTS/DSR pass through is disabled for a Telplex terminal port, the DSR
line for that port will remain a co12 VDC while power is applied
and the RTS input line will be ignored.
The factory default RTS/DSR pass through setting is disabled for
all terminal ports.
4.6.2 4.6.2 XON/XOFF FLOW CONTROL XON/XOFF FLOW CONTROL
The Telplex permits XON/XOFF to be enabled or disabled by port
independently, in the receive data (RX) and transmit data (TX)
directions. The description of handshaking assumes XON/XOFF to be
enabled in both directions. If XON/XOFF is disabled in one direction,
that direction will support hardware handshaking.

(RECV) (RECV)
When information is received by a Telplex terminal port, the data is
stored in a receive buffer and subsequently transmitted to the remote unit
through a composite port. If the receive buffer fills, the Telplex will send
an XOFF character signaling the terminal device that it cannot accept
more data. When the buffer empties to where it can accept more
characters, the Telplex will send an XON character.
