10.6.3 \Nn - 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.
Command: \Nn
n 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.)
