In error correction mode, the modem will signal a break through the active error
correction protocol, giving no indication of the length.
\B1-\B9Break length in 100 ms units. (Default = 3.) (Non-error corrected mode
only.)
Result Codes:
OK
If connected in data modem mode.
NO CARRIERIf not connected or connected in fax modem mode.
Note: When the modem receives a break from the remote modem, break is passed to
the DTE as follows: In non-error correction mode direct, the break length is passed;
in non-error correction mode normal and in error correction mode, a 300 ms break is
passed.
-Kn - MNP Extended
Services
Enables or disables conversion of a V.42 LAPM connection to an MNP 10
connection.
-K0 Disables V.42 LAPM to MNP 10 conversion. (Default.)
-K1 Enables V.42 LAPM to MNP 10 conversion.
-K2 Enables V.42 LAPM to MNP 10 conversion; inhibits MNP Extended
Services initiation during V.42 LAPM answer mode detection phase.
Result Codes:
OK
n = 0 or 2.
ERROR Otherwise.
--SEC=n - Enable/
Disable MNP10-EC
Enables or disables MNP10-EC operation. The command format is:
-SEC=n,[<tx level>]where <tx level> is the optional transmit level sub parameter.
-SEC=0 Disable MNP10-EC;
-SEC=1,[<tx level>]Enable MNP10-EC; the transmit level will be defined by the
sub parameter <tx level> range 0 to 30 (0 dBm to -30 dBm)
Result Codes:
OK
n=0, 1, or 1 and <tx level>=0 to 30
ERROR Otherwise
Example: AT-SEC=1,18 enables MNP10-EC and sets the transmit level to -18 dBm.
Note: If AT-SEC=0, the modem will automatically set AT-SEC=1 if the remote
modem indicates Cellular in the V.8 bis/V.8 phase or if a Cellular Driver is loaded
and the Cell Phone is attached.
