Command:

\Nn

Error Correction Mode Selection

Values:

 

n = 0–5, or 7

Default:

 

3

Description:

\N0

Non-error correction mode with data buffering (buffer mode;

 

 

same as &Q6).

 

\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

Default:

 

3

Description:

\Q0

Disables flow control (same as &K0).

 

\Q1

XON/XOFF software flow control (same as &K4).

 

\Q3

RTS/CTS hardware flow control (same as &K3).

Command:

\Tn

Inactivity Timer

Values:

 

n = 0, 1–255

Default:

 

0

Description:

\Tn

Sets the time (in minutes) that the modem waits after the last

 

 

character is sent or received before it disconnects. A value of

 

 

zero disables the timer. Applies only in buffer mode.
