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.
