AT Command Set

 

AT Command Reference (continued)

On

Return On-line to Data Mode

 

O0:

Instructs the modem to exit on-line command mode and return to data mode

 

(see AT Escape Sequence, +++).

 

O1:

This command issues a retrain before returning to on-line data mode.

 

O3:

This command issues a rate renegotiation before returning to on-line data mode.

Result Codes:

 

 

 

OK

n = 0, 1, 3

 

ERROR

Otherwise

P

Select Pulse Dialing

This command configures the modem for pulse (non touch-tone) dialing. Dialed digits are pulsed until a T command or dial modifier is received. Tone dial is the default setting.

Qn

Result Code Control

Result codes are informational messages sent from the modem and displayed on your monitor. Basic result codes are OK, CONNECT, RING, NO CARRIER, and ERROR. The ATQ command allows the user to turn result codes on or off.

Q0:

Q1:

Result Codes:

OK

ERROR

T

Select Tone Dialing

This command instructs the modem to send DTMF tones while dialing. Dialed digits are tone dialed until a P command or dial modifier is received. This is the default setting.

VnDCE Response Format

This command controls whether result codes (including call progress and negotiation progress messages) are displayed as words or their numeric equivalents. For the result code, see table 4.

V0:

Displays result codes as digits.

V1:
