4.21 End-to-End DTR Flow Control Screen
View the current status of end-to-end hardware flow control (via the DTR line)
used on this sub-channel and select, if desired, a new status.
There are applications in which end-to-end (DTE-to-DTE) software flow control
cannot be used, but the end-to-end flow control function described in
Section 4.20
is nevertheless essential.
In these applications, the Multiplexor can be configured to use “end-to-end”
DTR flow control by setting ON in this screen.
In this mode, the Multiplexor monitors the DTR line contained in the local
sub-channel RS-232 interface, and transmits the status of this line to the remote
Multiplexor. The remote Multiplexor then supplies to the DTE connected to it the
flow control commands according to the Mux-to-DTE flow control modes selected
at the remote Multiplexor.
Selecting OFF on this screen disables the transmission of flow control
commands to the remote Multiplexor when the DTR line changes state.
Screen selections are as follows:
Code numbers 1 and 2 list the available selections of end-to-end hardware flow
control status: on or off.
Code Q is used to return to the SUB-CHANNEL CONFIGURATION screen.
The CURRENT STATE line shows the current status of end-to-end hardware
flow control.
To change the status of end-to-end hardware flow control used on this sub-
channel, type the appropriate code number. The new selection appears in the
