*E

Enable/Disable Network Operations

 

If PINs are required for network access, this command enables and disables access to the network.

 

Use of PINs can be required by the AT\P+ or the AT^F1 command. If required, access to the CDPD

 

network is denied until the proper PIN number is entered with the AT*E+ command. Specifically the

 

Register (AT\Rn) and the Dial (ATDx) commands are not allowed. Once the PIN is entered, network

 

access is allowed until the modem is power cycled, or until access is disabled by the AT*E- command.

 

The modem becomes BLOCKED after three consecutive incorrect PIN entries are made. This condition

 

can be cleared with the AT*U command.

 

Format:

 

 

AT*E+<pin>

PIN entry; the user is prompted for the PIN when establishing connection to the

 

 

network. The default PIN value is 0000.

 

AT*E-

Disallow network access commands and require PIN reentry in order to reestablish

 

 

network connection.

 

Result codes:

 

 

OK

Valid argument
