DART 200 CDPD Modem User’s Guide

F DART AT Command Set

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.
