Transmit Break / Set Break Length — \B
The
\B
commands tell the local modem to send a break signal to the
remote modem. In all modes except direct,
S79
determines the length
of the break sent to the DTE by the modem receiving a break signal over
the link.
S79
may be set directly or via
\Bn
where
n
=1-255 in 20 ms
increments. The default is 35 (700 ms).
Set Auto-Reliable Buffer — \C
This determines whether or not a modem in reliable mode will buffer
data received from a modem that is not in reliable mode during the 4
seconds in which the modems try to establish a reliable link. Use these
commands when the modem is in the auto-reliable mode and is expected
to process a call from a modem not in a reliable mode.
V.42bis Data Compression — %C
The
%C
command determines application of data compression while
running LAPM protocol.
