/STATE=option

    Specifies whether LAT connections are allowed. The three options
    for STATE are:

    ON       Starts the LAT port driver (and LAT protocol software)
             on your node.

             Digital strongly recommends that the LATCP command SET
             NODE/STATE=ON be executed before any LTA application or
             dedicated ports are created (use the format provided in
             SYS$MANAGER:LAT$SYSTARTUP.TEMPLATE) for two reasons:

             o  It ensures that LTDRIVER will delete any leftover
                LTA devices that have a reference count of 0 and are
                explicitly marked for deletion (using the $DASSGN
                system service or the LATCP DELETE PORT command,
                for example). Because every LATCP management port
                (LATCP$MGMT_PORT) that was created by the previous
                LATCP invocation is deleted, no conflicts result with
                the LAT application ports or newly created dedicated
                ports.

             o  The deletion of leftover LTA devices with a reference
                count of 0 minimizes the use of nonpaged pool memory.

    OFF      Stops the LAT port driver (and LAT protocol software) on
             your node. Any existing LAT connections are aborted. Any
             characteristics that you changed or set with LATCP are
             lost.

             To start the LAT protocol on your node again, invoke
             LAT$STARTUP.COM. The LAT characteristics defined in
             LAT$SYSTARTUP.COM will take effect.
    SHUT     Specifies that new LAT connections cannot be created on
             your local node, but existing connections may continue.
             The LAT protocol continues running only until the last
             active session disconnects, (after which LTDRIVER will
             stop). At that time, your node changes to the OFF state.

                                 CAUTION

       If you stop the LAT software by specifying either the SET
       NODE/STATE=OFF or SET NODE/STATE=SHUT command, the LAT
       print symbiont (LATSYM) will shut down all print queues that
       it is processing. The system will then generate an OPCOM
       message indicating that the print queues are stopped. You
       must manually restart those print queues.

    If you do not specify the /STATE=option qualifier, the default is
    that the LAT port driver and LAT protocol software on your node
    will be started (ON).
