13. END-TO-END DTR FLOW CONTROL Screen
Purpose:
View the current status of end-to-end hardware flow control (by means of
DTR line) used on this sub-channel and select, if desired, a new status.
Description:
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 subsection
12 is nevertheless essential. In these applications, the MiniStat-Four can be
configured to use “end-to-end” DTR flow control by setting it ON at this screen.
In this mode, the MiniStat-Four monitors the DTR line contained in the standard
RS-232 interface, and transmits the status of this line to the remote MiniStat-Four.
The remote MiniStat-Four then sends the remote DTE flow-control commands
according to the MiniStat-Four-to-DTE flow control modes selected at the remote
MiniStat-Four.
Selecting OFF at this screen disables the transmission of flow-control commands to
the remote MiniStat-Four when the DTR line changes state.
Screen selections are as follows:
Code numbers 1 and 2 list the available selections for end-to-end hardware
flow-control status: (1) ON or (2) OFF.
