%B—View Numbers in Blacklist
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 that prohibit repeat calls to the same number through automatic dialing.

Blacklisting is a method of handling failed or troubled calls encountered during automatic dialing.
Result codes:
• <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.
%C<value>—Data Compression Control
Use this command to enable or disable data compression. This command enables or disables V.44,
V.42bis, and MNP class 5 data compression. The command overwrites the current status of the +DCS
command. The command is also overwritten by changes made by the +DCS command. Online changes
do not take effect until a disconnect occurs.
Result codes:
• OK if <value> = 0, 1.
ERROR if <value> ≠ 0, 1.

1. 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. For more information on how blacklisting works, see the Controller-Based Homologation Reference
Manual.
