Sierra Wireless, Inc. F-24
Table F-4. Commands beginning with asterisk (*) (cont.)
*U Unblock Modem - PIN Access
Can be used to unblock the modem if the PIN is forgotten or is entered incorrectly 3 times. The modem
is unblocked for the express purpose of entering a new PIN. Whenever this command is executed,
follow it immediately by the Set PIN command (AT\P=) to set a new (or restore the old) PIN value
when the current PIN is not subject to validation.
If the Set PIN command is not executed the modem remains in the unblocked state until the next power
cycle, or until a command requiring the PIN is successfully executed.
The default unblocking key is 12345678.
If the unblocking key is entered incorrectly 10 times in succession this command also becomes
BLOCKED. This condition can be cleared by using the AT^C command. Refer to Chapter 3, CDPD
Security Features, Modem security management, for more information.
