Auto-Reliable Buffer Control (\C)
This command controls the auto-reliable buffer operation. This feature can be used to reduce
connect time to systems using non-error control modems.
Parameters: 0, 1, 2
n = 0
Does not buffer data during error-control negotiation
(Default)
.
n = 1
Buffers data received from the remote modem while
waiting for error correction protocol handshaking. If
error control is negotiated, the modem discards the
buffer contents and proceeds with error correcting
operation. If instead a fallback to speed buffering
occurs, the buffer contents are delivered to the serial
port. The buffer capacity is 200 characters.
n = 2
Does not buffer data during error control negotiation.
Switches immediately to speed buffered operation
(without error control) if the character defined by the
%A command is received. This setting is useful in
calling a system for which the first character sent is
known and where several different types of modems
are attached.
Break Control (\K)
This command sets Break Control. This command controls the sequence of events when a
break is initiated.
