Hacker Protection/Locking function.
This function is related only to Password/Dialback-Mode 1,
Protected System, and is controlled by register +S18.
Factory setting for +S18 is 255
and it can be set to any value in
the range 1 - 255 by the command: _
AT+S18=<number>p*al,
There are 4 ranges of +S18 , and the function operates different
for each range :
129-255:
+$18
will be decremented by one ( until the value 128 is
reached) whenever the modem hangs up because a wrong
password is entered. Locking will never occur.
128:
+$18 will not be decremented when entering wrong
password(s).
1-127:
The register will be decremented by one (until the value zero is
reached) whenever the modem hangs up because wrong
password is entered.
Locking occurs.
Access to host is no longer possible. (This value can not be set
directly by a command.)
Setting +$18 in range 129 to 255, means that the modem will
only count interception attempts and never lock up.
Setting +S18 in range (3), 1 to 127, means that the modem will
count interception attempts and locking will occur when the
value of zero is reached and access to host is then not available.
When +S18=0 and +P0Q1 is used a caller will receive the
message:
ACCESS DENIED - REMOTE MODEM DISCONNECTS
and the modem will disconnect as follows :
+00,+01,+02:
Hang-up will follow after 3 Sec.
+03:
Hang-up will follow after 8 Sec.
The modem
is now "Locked".
