5 Ancillary Device Control
This parameter determines method of flow control used by the PAD to temporarily halt and
restart the flow of data from the DTE during a call.
Option
Description
0 No flow control
1 XON/XOFF flow control
3 RTS/CTS flow control (not a standard X.3 parameter)
6 Suppression of PAD Service Signals
This parameter determines whether or not the “PAD>” prompt and/or Service/Command
signals are issued to the DTE.
Option
Description
0 PAD prompt and signals disabled
1 PAD prompt disabled, signals enabled
4 PAD prompt enabled, signals disabled
5 PAD prompt enabled, signals disabled
7 Action on Break (from DTE)
This parameter determines the action taken by the PAD on receipt of a break signal from
the DTE.
Option
Description
0 No action
1 Send an X.25 interrupt packet
2 Send an X.25 reset packet to the remote system
4 Send an X.29 indication of break
8 Escape to PAD command state
16 Set PAD parameter 8 to 1 to discard output
Multiple actions on receipt of break are possible by setting this parameter to the sum of the
appropriate values for each action required.
For example, when parameter 7 is set to 21 (16 + 4 + 1), an X.25 interrupt packet is sent
followed by an X.29 indication of break and then parameter 8 is set to 1.
You should NOT set this parameter to 16 because the remote system would receive no
indication that a break had been issued and output to the DTE would therefore remain
permanently discarded. If you need to use the discard output option, use it in conjunction
with the X.29 break option so that on receipt of the X.29 break the remote system can re-
enable output to your DTE using parameter 8.
