       /LOCK_STATE
       /NOLOCK_STATE (default)

    Specifies that the state set by the /SET_STATE qualifier remain
    in effect until explicitly changed. (By default, the /SET_STATE
    qualifier is in effect only for the next definable key you press
    or the next read-terminating character that you type.) This
    qualifier can be specified only with the /SET_STATE qualifier.
