!\N – Operating Mode
This command controls the preferred error correcting mode to be negotiated in a subse-
quent data connection.
AT!\N0Selects 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 fail-
ure 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 ID-90 is in command mode after issuing an escape sequence out of an existing
connection, ATO brings the ID-90 back to data phase.
Must be the last command in AT command line.

ber of the calling party.
