10.3.1 General modem control commands
Command: \N
Operating mode − error correction
Checks the preferred error correction operating mode which is set automatically when a
subsequent data connection is established. This command is defined by the third party
manufacturer’s firmware configuration.
Command Default
setting Values defined Result codes
\N 5 \N0 Selects the buffered operating mode at normal speed
(deactivates the error correction operating mode).
(Forces &Q6). OK
otherwise ERROR
\N1 Serial interface selected: Selects the direct operating
mode and equals &M0, Q0 operating mode. (Forces
&Q0). Parallel interface selected: the same as \N0.
\N2 Selects the reliable (error correction) operating mode.
The modem attempts to establish a LAPM connection
first, then an MNP connection. If no reliable
connection is established, the modem hangs up.
(Forces&Q5, S36=4 and S48=7).
\N3 Selects the auto−reliable operating mode which works
in the same way as \N2, except for the fact that the
inability to establish a reliable connection causes the
modem to go back to the buffered operating mode at
normal speed. (Forces &Q5, S36=7 and S48=7).
\N4 Selects the LAPM error correction operating mode. If it
is not possible to establish a LAPM error correction
connection, the modem hangs up. (Forces &Q5 and
S48=0). Note: The −K1 command can overwrite an \N4
command.
\N5 Selects the MNP error correction operating mode. If it
is not possible to establish an MNP error correction
connection, the modem hangs up. (Forces &Q5, S36=4
and S48=128).
Command: &F
Restores the configuration provided by the factory (profile)
The modem loads the preset configuration provided by the factory (profile). The default
settings made by the factory are marked for each command and in the S−parameter
descriptions. A configuration (profile) consists of a subset of S−parameters.
Command Default

− − &F0 Restoring configuration 0 provided by the factory. OK
ERROR if the
modem has
established a
connection.
&F Restoring configuration 1 provided by the factory.
