Command Reference Manual
1199 3-3
3.2.1.4 \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<mode>
Defined Values
<mode> 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 <mode> = 0 to 5.
ERROR Otherwise.
