\N n Error Correction Mode Selection
n = 0–5
3
\N0 Normal (non-error correction) mode with data buffering.
(Forces &Q6.)
\N1 Direct mode. Equivalent of &M0 and &Q0 modes. (Forces &Q0.)
\N2 V.42/MNP reliable (error-correction) mode. The modem at-
tempts first a V.42 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.)
\N3 V.42/MNP auto-reliable mode. The modem attempts first to
connect in V.42 mode, then in MNP mode, and finally in non-
error-correction mode with data buffering. (Forces &Q5, S36=7,
and S48=7.)
\N4 V.42 (LAPM) reliable mode.If the modem cannot make a V.42
connection, it disconnects. (Forces &Q5 and S48=0.) Note: The
-K1 command can override the \N4 command.
\N5 MNP reliable mode.If the modem cannot make an MNP con-
nection, it disconnects. (Forces &Q5, S36=4, and S48=128.)
\V n Single Line Connect Message
n = 0 or 1
0
\V0 Disables single line connect message. Connect messages are
controlled by the X and W command settings.
\V1 Enables single line connect messages in the format: CONNECT
<Serial Port Speed></Modulation></Protocol></Compres-
sion></Line Speed>/<Voice and Data>. Connect messages are
displayed in the single line format subject to the commands V
and Q. In non-verbose mode (V0), single line connect messages
are disabled and a single numeric result code is generated for
CONNECT.

This extended-format command selects modulation and, op-
tionally, enables or disables automode, specifies the lowest and
highest connection rates, selects µ-Law or A-Law codec type,
and enables or disables robbed bit signaling detection using
one to five subparameters.
The command format is: +MS=<mod>[,[<automode>]
[,[<min_rate>][,[<max_rate>][,[<x_law>][,[<rb_signaling>]]]]]]<CR>
Subparameters that are not entered retain their current value.
Commas separate optional subparameters, and should be in-
serted to skip a subparameter. Example: +MS=,0,<CR> dis-
ables automode and keeps all other settings at their current
values.
+MS? Reports current options in the format: +MS:
<mod>,<automode>,<min_rate>,<max_rate>,<x_law>,<rb_signaling>
Example: +MS: 56,1,300,56000,0,0.
