       /NODE=remote-node-name

    Specifies the name of a terminal server (or a remote node that
    supports outgoing connections) to be logically associated with
    the specified application port on your node. The server supports
    a remote device. Note that you can set up an application port
    on your local node and associate the port with a dedicated port
    on a remote LAT service node. The remote port is dedicated to an
    application service.
