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..
AT%A<value>
0 Disables adaptive answer result codes.
1 Enables adaptive answer result codes.
0
OK if <value> = 0, 1.
ERROR if <value> ≠ 0, 1

View Numbers in Blacklist

Blacklisting is a method of handling failed or troubled calls encountered during
automatic dialing. This command is only used to display the contents of the blacklist
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.
AT%B
N/A
<list of phone numbers and their status> if country supports blacklisting.
OK if no failed calls occur.
ERROR if country selection does not support blacklisting.
