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

    Specifies that a logical port on your local node is dedicated
    to an application service. When users on a terminal server (or
    on another node that supports outgoing connections) request
    a connection to this service name, they are connected to the
    dedicated port. See the OpenVMS I/O User's Reference Manual for a
    description of programming an application service.

    After creating a dedicated port on a node, use the SET PORT
    /SERVICE command to map this port to a service.
