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
