DART 200 CDPD Modem User’s Guide F DART AT Command Set
Sierra Wireless, Inc. F-26
Clearing BLOCKED status
When the Service Provider key is BLOCKED and an AT^P+ command
is issued, the modem waits 30 seconds before responding with the
BLOCKED response. This is intended to impose a barrier to any
computer-generated attempt to determine the key value by hackers.
Furthermore, at this point only the Master Key clears the BLOCKED
condition.
To clear the BLOCKED condition the AT^P+ command is used with the
Master Key; the default Master Key value is 34895400. This re-enables
the Service Provider key until the modem is power cycled or reset and
the BLOCKED condition is restored.
To permanently clear the blocked condition an AT^C command must be
issued following the AT^P+
<master key>.
