lock [ password "<password_string"> ]

        Lock the keyboard or define a password string.

        If 'password' is given then <password_string> is saved as the
        unlock string.

        If no parameters are supplied, the keyboard becomes locked when a
        password was specified earlier.

        If the keyboard is locked, the password is requested.  If a
        correct password is supplied, the keyboard becomes unlocked.

        The setting of the password and locking of the keyboard can only
        been done at the system console keyboard or in the /autoexec.nos
        startup file.  The password can not been displayed.
