CHAPTER 4: AT Commands, S-Registers, and Result Codes
Command: %A Adaptive Answer Result Code Enable
Values: n=0 or 1
Defaults: 0
Description: The %A command controls whether the DATA and
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.
%A0 Disables adaptive answer result codes.
%A1 Enables adaptive answer result codes.
Command: %B View Numbers in Blacklist

appears.
