Modem AT Commands & S-Registers

must be connected to a modem with a V.42 protocol (MNP or LAP-M).

The V.42 standard includes MNP Class 3 and 4 and LAP-M error correction

methods.

\N5 enables auto-reliable mode. During the handshaking procedures at the

start of the online connection, the modem queries whether the other modem

is using V.42 error correction. If the modem determines that the other

modem is using V.42, it switches itself into reliable (V.42) mode and

enables error correction. If it determines that the other modem is not using

V.42, the modem remains in non-error correction mode. (This is the same as

\N3 and \N7.)

\N7 enables auto-reliable mode. During the handshaking procedures at the

start of the online connection, the modem queries whether the other modem

is using V.42 error correction. If the modem determines that the other

modem is using V.42, it switches itself into reliable (V.42) mode and

enables error correction. If it determines that the other modem is not using

V.42, the modem remains in non-error correction mode. (This is the same as

\N3 and \N5.)

%Cn Data Compression

n = 0 or 1

Default: %C1

The %C command allows you to disable data compression. Data

compression is normally enabled.

%C0 disables V.42bis/MNP 5 data compression.

%C1 enables V.42bis/MNP 5 data compression.

Immediate Action Commands

Use immediate action commands to obtain information about AT commands

and current modem settings.

A/ Repeat Last Command

Default: None

Type A/ to repeat the previous command. Do not precede this command

with AT or press ENTER to execute it.
