AT Commands for CX81801/CX06833/CX81300/CX06827 Modems Reference Manual
102184B Conexant 3-5
\N - Operating Mode
This command controls the preferred error correcting mode to be negotiated in a
subsequent data connection. This command is affected by the OEM firmware
configuration.
Syntax
\N
Defined Values
Decimal number which corresponds to the selected mode.
0 Selects normal speed buffered mode (disables
error-correction mode). (Forces &Q6.)
1 Serial interface selected - Selects direct mode
and is equivalent to &M0, &Q0 mode of
operation. (Forces &Q0.)
Parallel interface selected - Same as \N0.
2 Selects reliable (error-correction) mode. The
modem will first attempt a LAPM connection
and then an MNP connection. Failure to make a
reliable connection results in the modem hanging
up. (Forces &Q5, S36=4, and S48=7.)
3 Selects auto reliable mode. This operates the
same as \N2 except failure to make a reliable
connection results in the modem falling back to
the speed buffered normal mode. (Forces &Q5,
S36=7, and S48=7.)
4 Selects LAPM error-correction mode. Failure to
make an LAPM error-correction connection
results in the modem hanging up. (Forces &Q5
and S48=0.) Note: The -K1 command can
override the \N4 command.
5 Selects MNP error-correction mode. Failure to
make an MNP error-correction connection
results in the modem hanging up. (Forces &Q5,
S36=4, and S48=128.)
Result Codes
OK = 0 to 5.
ERROR Otherwise.
