\Nn – Operating Mode
This command determines which error correcting mode will be used during a link negotiation.
\N0 Normal speed buffered mode. (Forces &Q6)
\N1 Selects direct mode and is equivalent to &M0, &Q0 (Forces &Q0)
In this mode RS-232/V.24 data is directly connected to the data pump, which results
in the lowest possible delay time. This is useful in the case of polled systems like PLC-
systems and similar, where the response time is critical.
\N2 Selects reliable (error-correction) mode. The modem will first attempt a LAPM connec-
tion and then an MNP connection. Failure to establish a reliable connection results in the
modem hanging up. (Forces &Q6 and sets S36=4 and S48=7)
\N3 Selects automatically reliable mode. This mode operates the same way as \N2 except
failure to establish a reliable connection results in the modem going to \N0 mode.
(Forces &Q5 and sets S36=7 and S48=7.) (Default)
\N4 Selects LAPM error-correction mode. Failure will results in the modem hanging up.
(Forces &Q5 and sets S48=0)
The –K1 command overrides if this is set.
\N5 Selects MNP error-correction mode. Failure will results in the modem hanging up.
(Forces &Q5 and sets S36=4 and S48=128.)

On – Return to Communication Mode
This command is used for returning to communication mode after the command (+++) has been
used to interrupt communication temporarily.
O0 Returns from command mode to line without using the possibility to change the commu-
nication speed, compression etc.
O1 Returns from command mode to line with ”re-negotiation” of connection parameters.

Qn – Result Code Control
This command controls whether or not result codes will be returned to the terminal after instructions
have been sent to the modem. This applies to for example OK, CONNECT, BUSY etc.
Q0 Enables sending of result codes to the terminal. (Default)
Q1 Disables sending of result codes to the terminal.
