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+
Security Features, Modem security management, for more information.
<s> =IP Address of the modem followed by /n where <n> is the position in the
modem's NEI list where the IP Address is stored. Valid values for n are 0 to 9
with the default being 0.
The form of the IP address is nnn.nnn.nnn.nnn/n, for example,
155.174.21.100/5.
This form of the AT^A command is used to remove the IP address in slot n of
the NEI list. The ASN and ARN for slot n is reset to 0.
