AT-SEC=n Enable/Disable MNP10-EC

Enables or disables MNP10-EC operation. The command format is:

AT-SEC=n, [<tx level>] where <tx level> is the optional transmit level sub

parameter.

AT-SEC=0 Disable MNP10-EC; the transmit level is that defined in S91.

AT-SEC=1, [<tx level>] Enable MNP10-EC; the transmit level will be defined

by the sub parameter <tx level> range 0 to 30 (0 dBm to -30 dBm), the default

<tx level> (<tx level> not specified) is the S91 value.

ATX0 Disables monitoring of busy tones unless forced otherwise

by country requirements; send only OK, CONNECT, RING, NO

CARRIER, ERROR, and NO ANSWER result codes. Blind dialing is

enabled/disabled by country parameters. If busy tone detection

is enforced and busy tone is not detected, NO CARRIER will be

reported. 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 000b is written to S22 bits

6, 5, and 4, respectively.

ATN1 Auto mode detection is enabled (equivalent to setting the

+MS<automode> sub parameter to 1). A subsequent handshake will be

conducted according to the auto mode algorithm supported by the

modem, e.g., according to the contents of S37 or, if S37 is zero, starting

at 28800 bps V.34 (RC288). This command is also equivalent to F0

(RC144). (Default.)

ATOn Return to On-Line Data Mode

This command determines how the modem will enter the on-line data

mode. If the modem is in the off-line command mode (no connection),

ERROR is reported.

ATO0 Enters on-line data mode without a retrain. Handling is

determined by the Call Establishment task. Generally, if a

connection exists, this command connects the DTE back to the

remote modem after an escape(+++).

ATO1 Enters on-line data mode with a retrain before returning to

on-line data mode.

ATP Set Pulse Dial Default

This command forces pulse dialing until the next T dial modifier or

T command is received. It also sets S14 bit 5. As soon as a dial

command is executed which explicitly specifies the dialing mode for that

particular call (e.g.,ATDT...), this command is overridden so that all

future dialing will be tone dialed. This command may not be permitted in

some countries.
