selected and dial tone is not detected, NO CARRIER will be reported instead of NO DIAL

TONE. The value 000b is written to S22 bits 6, 5, and 4, respectively.

X1 Disables reporting of busy tones unless forced otherwise by country requirements; send only

OK, CONNECT, RING, NO CARRIER, ERROR, NO ANSWER, and CONNECT XXXX

(XXXX = rate). Blind dialing enabled/disabled by country parameters. If busy tone

detection is enforced and busy tone is detected, NO CARRIER will be reported instead of

BUSY. If dial tone detection is enforced or selected and dial tone is not detected, NO

CARRIER will be reported instead of NO DIAL TONE. The value 100b is written to S22

bits 6, 5, and 4, respectively.

X2 Disables reporting of busy tones unless forced otherwise by country requirements; send only

OK, CONNECT, RING, NO CARRIER, ERROR, NO DIALTONE, NO ANSWER, and

CONNECT XXXX. If busy tone detection is enforced and busy tone is detected, NO

CARRIER will be reported instead of BUSY. If dial tone detection is enforced or selected

and dial tone is not detected, NO DIAL TONE will be reported instead of NO CARRIER.

The value 101b is written to S22 bits 6, 5, and 4, respectively.

X3 Enables reporting of busy tones; send only OK, CONNECT, RING, NO CARRIER,

ERROR, NO ANSWER, and CONNECT XXXX. Blind dialing is enabled/disabled by

country parameters. If dial tone detection is enforced and dial tone is not detected, NO

CARRIER will be reported. The value 110b is written to S22 bits 6, 5, and 4, respectively.

X4 Enables reporting of busy tones; send all messages. The value 111b is written to S22 bits 6,

5, and 4, respectively. (Default.)

Result Codes:

OK n = 0 to 4.

ERROR Otherwise.

Refer to 12-Modem Result Codes for more information.

10.2.20 Zn - Soft Reset and Restore Profile

The modem performs a soft reset and restores (recalls) the configuration profile according to the

parameter supplied. If no parameter is specified, zero is assumed.

Z0 Soft reset and restore stored profile 0.

Z1 Soft reset and restore stored profile 1.

Result Codes:

OK n = 0 or 1.

ERROR Otherwise.

10.3 AT& Command Set

10.3.1 &Cn - RLSD (DCD) Option

The modem controls the RLSD output in accordance with the parameter supplied. The parameter

value, if valid, is written to S21 bit 5.

&C0 RLSD remains ON at all times.

&C1 RLSD follows the state of the carrier. (Default.)
