/LOCAL_ECHO
       /NOLOCAL_ECHO (default)

    Controls whether the terminal echoes characters locally (rather
    than the host echoing them) for command level terminal functions.
    (Do not use the /LOCAL_ECHO qualifier with utilities that require
    control over echoing, such as line editing or EDT's screen mode.)

                                 CAUTION

       When logging in to terminals with the LOCAL_ECHO
       characteristic, the OpenVMS system has no control over the
       echoing of passwords.
