%A
Adaptive Answer Result Code Enable
Description:
The %A command controls whether the DATA or FAX result codes will be sent by the
modem. The modem must be in fax mode for this command to work. Also, the
modem must be set to +FAA=1, which enables the modem to distinguish between a
fax and a data call. When these commands are enabled, the modem sends DATA to
the computer when it detects data tones and FAX when it detects fax tones. These
strings are used by some servers to select the appropriate communication program..

AT%A<value>
Values:
0
1
Default:
0
Result Codes:
OK if <value> = 0, 1.
