XE1401 AT Commands (continued)
%L - Read Received Signal Level - AT%L permits the user Host initiates break with \B command on Reliable link.
to read the magnitude of the recevie singal in dBm.
n=0 Purge buffers and immediately transmit break
%Q - Read Line Signal Quality - AT%Q permits the user to
read the EQM value of the recevied signal.
n=1 Same as n=0
n=2 Immediately transmit break
n=3 Same as n=1
\An - MNP Block Size - AT|An sets the block size for MNP
n=4 Transmit break in sequence w data
data packets.
n=5 Same as n=4
n=0 Maximum 64 characters
n=1 Maximum 128 characters
n=2 Maximum 192 characters
n=3 Maximum 256 characters*
\Nn - Error Correction Selection - AT\Nn determines how
the modem handles error control negotiations.
n=0 Normal Mode, no error correction
n=1 Direct Mode, no data bufferring, no error correction
\Bn - Transmit Break - AT\Bn selects the duration of the
n=2 Reliable Mode, error correction required
break signal sent. Break = n x 100 msec.
n=3 Auto Reliable Mode, accept either error controlled or
\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*
non-error controlled links
n=4 V42 Reliable Mode, LAPM required
n=5 MNP Reliable Mode, MNP required
\Vn - Single Line Result Codes - AT/Vn determines if the
Connect response is issued in a single line format. The single
line format is shown. CONNECT<DTE Speed><Modulation>
<Protocol><Compression><Link Speed>
n=0 Responses per ATX, ATW and S95*
n=1 Single Line Responses
Break received from host with Direct link .
n=0 transmit break, then enter on-line command mode
n=1 Immediately send break
n=2 Enter command mode; do not transmit break signal
n=3 same as n=1
n=4 same as n=0
n=5 same as n=1*
Break received from modem w 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*
-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 detect.
-SEC=n,t - MNP10-EC This comman controls the error correc-
tion protocol for cellular links, MNP10-EC.
n=0 No MNP10-EC error correction supported
n=1 Enable MNP10-EC protocol with Transmit Level at -t
dBm where t can be any value from 0 to 30.
