N – Set line baudrate V.110
This command will respond with OK without any functionality after it. V.110 baudrates
can be set with AT**BRN.
!\N – Operating Mode
This command controls the preferred error correcting mode to be negotiated in a
subsequent data connection.
AT!\N0
Selects normal speed buffered mode
(disables error-correction mode).
AT!\N1
Same as !\N0
AT!\N2
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.)
AT!\N3
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 S36=7, and S48=7,
(default)
AT!\N4
Selects LAPM error-correction mode. Failure to make an LAPM
error-correction connection results in the modem hanging up.
(Forces S48=0.)
Note: The !-K1 command can override the !\N4 command.
AT!\N5
Selects MNP error-correction mode. Failure to make an MNP
error-correction connection results in the modem hanging up.
(Forces S36=4, and S48=128.)
O – Return to online state
If the IDW-90 is in command mode after issuing an escape sequence out of an existing
connection, ATO brings the IDW-90 back to data phase.
