42 Blacklisting - The Si2493/57/34/15/04 does not dial the
same number more than two times in S44 seconds.
An attempt to dial a third time within S44 seconds
results in a “BLACKLISTED” result code. If the black-
list memory is full, any dial to a new number will result
in a “BLACKLIST FULL” result code. Numbers are
added to the blacklist only if the modem connection
fails. The %B command lists the numbers on the
blacklists.
