Command	Result
AT+CPWD=?	Displays a list of the passwords supported. These cur-
	rently include the PIN, device code and PIN2.

<old password>,	relevant password. When changing the password, you
<new password>	must enter both the old and new password. This ensures
	that changes can be made only if access is authorized.
