\N1

Direct mode.

 

 

\N2

MNP reliable mode. If the modem cannot make an MNP connection, it disconnects.

 

 

\N3

V.42/MNP auto-reliable mode. The modem attempts first to connect in V.42 error

 

 

 

correction mode, then in MNP mode, and finally in non-error correction (buffer) mode

 

 

 

with continued operation.

 

 

\N4

V.42 reliable mode. If the modem cannot make a V.42 connection, it disconnects.

 

 

\N5

V.42, MNP, or non-error correction (same as \ N3).

 

 

\N7

V.42, MNP, or non-error correction (same as \ N3).

Command:

\Qn

Flow Control Selection

Values:

 

n = 0, 1, or 3
