Adaptive Answer Result Code Enable
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..

View Numbers in Blacklist
Blacklisting is a method of handling failed or troubled calls encountered during

when blacklisting is active. It does not affect the functionality associated with
blacklisting.
When the blacklisting option is active, use this command to display the telephone
numbers and status of any failed or troubled calls. The blacklisting option is
associated with the country selection. Some countries have national requirements
which prohibit repeat calls to the same number through automatic dialing.
