\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.)
2 Parallel interface selected - Same as \N0.
3 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.)
4 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.)
5 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.
6 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.
I - Identification
This command causes the modem to reports the requested result according to the
command parameter.
Syntax I<value>
Defined Values
<value> Decimal number corresponding to the selected information.
0 0 Reports product code, e.g., “56000”.
1 Reports the least significant byte of the stored
checksum in decimal. Reports 255 if the prestored
checksum value is FFh.
2 Reports "OK".
3 Reports identification codes.
For the SmartACFL, SmartACF, and SC56D, the codes
are in the form RevisionName-Modulation_Model,
