Library /sys$common/syshlp/latcp$help.hlb SET, PORT, Qualifiers, /APPLICATION  *Conan The Librarian (sorry for the slow response - running on an old VAX)

    Specifies that a port on the local node is an application port,
    logically associated with a port on a terminal server or a
    dedicated port on another LAT service node. The terminal server
    port supports a device (for example, a printer). If the port
    is used to support a printer, the print queue is established in
    a startup command procedure. See the OpenVMS System Manager's
    Manual for a description of configuring remote printers on a
    terminal server.

    If you do not specify a port type, the default port type is
    APPLICATION.
