\Kn- Break Control
– AT\Kn determines how the modem will handle a break signal.
Break received from host with reliable link
n=0 Enter on-line command mode; do not transmit break
n=1 Purge buffers, immediately transmit break
n=2 Same as n=0
n=3 Immediately send break
n=4 Same as n=0
n=5 Send break in sequence with data
Break received from host with direct link
n=0 Immediately transmit break, then enter on-line command mode
n=1 Immediately send break
n=2 Enter command mode, but do not transmit break
n=3 Same as n=1
n=4 Same as n=0
n=5 Same as n=1
Break received from modem with normal link
n=0 Purge buffers, immediately send break to the host
n=1 Same as n=0
n=2 Immediately send break to the host
n=3 Same as n=2
n=4 Send break in sequence with data
n=5 Same as n=2
Host initiates break on reliable link
n=0 Purge buffers and immediately transmit break
n=1 Same as n=0
n=2 Immediately transmit break
n=3 Same as n=1
n=4 Transmit break in sequence with data
n=5 Same as n=4
\Nn- Error Control Selection
-AT\Nn determines how the modem will handle error control negotiations
n=0 Normal mode, no error correction
n=1 Direct mode, no buffering, no error correction
n=2 Reliable mode, error correction required
n=3 V.42 Auto-reliable mode, accept either an error controlled or non-error controlled link
n=4 V.42 Reliable mode, LAPM required
n=5 MNP required
-Kn- MNP Extended Services
– AT-Kn determines how the modem handles MNP10
n=0 No LAPM to MNP10 conversion
n=1 LAPM to MNP10 conversion
n=2 LAPM to MNP10 conversion but no MNP extended service during V.42 LAPM answer mode
