APPENDIX A. AT COMMANDS

ACTIVE Professional External Modem User’s Manual

14

ATLn *

Speaker volume

Default :   2

ATL0

Selects low speaker volume

ATL1

Selects low speaker volume

ATL2

Selects medium speaker volume

ATL3

Selects high speaker volume

ATMn *

Speaker control

Default :   1

ATM0

Speaker is always off

ATM1

Speaker is on during handshaking in call establishment but is
turned off while the modem is receiving a carrier signal from
a remote modem

ATM2

Speaker is always on

ATM3

Speaker goes off while the modem is receiving a carrier

signal from a remote modem and while the modem is dialling.
However, speaker is on during answering

ATNn *

Modulation handshake

Default :   1

ATN0

Requires the speed of the connection be that specified by the
value held in S37; if S37=0, the speed of the connection must
match that at which the last AT command was issued. If the
selected speed can be achieved using more than one
communication standard (e.g., Bell 212A or ITU-T V.22 at
1200bps), the modem also refers the selection made with the
ATB command

ATN1

Permits handshaking to occur at any speed supported by both
modems. Enables automode detection. The ATB command is
ignored in this mode and the modem attempts only ITU-T
mode connections.

ATOn

Return to the on-line state

Default :   0

ATO0

Causes the modem to return to the data mode

ATO1

Causes the modem to return to the data mode and to initiate a
retrain

ATP *

Set pulse dial as default

ATQn *

Result code display

Default :   0

ATQ0

Allows the modem to send result codes to the DTE

ATQ1

Prohibits the modem from sending result codes to the DTE

ATSn

Establish S register n as the default register

ATSn?

Reading S registers

Reads the contents of the S register. All the S registers may be read.

ATSn=x

Writing to S registers

Writes the value of x to the specified S register n
