Library /sys$common/syshlp/nclhelp.hlb Entity Hierarchy, DDCMP (OpenVMS VAX), Subentities  *Conan The Librarian (sorry for the slow response - running on an old VAX)

    The entity hierarchy for the DDCMP module is:

    Node___DDCMP____Link___Logical_Station
                  |
                  |_Port

    The DDCMP entity is the top-level entity in the hierarchy of
    entities belonging to the DDCMP module.

    The DDCMP LINK entity defines the attributes of a link to a
    communications port that uses the DDCMP protocol. The link-name
    refers to the link managed by this command.

    The DDCMP LINK LOGICAL STATION entity manages a link to a remote
    station. The link-name is the DDCMP link associated with the
    logical station and the station-name refers to the logical
    station managed by this command.

    A DDCMP PORT entity represents an access point to the Data Link
    layer service offered by ddcmp. Ports are created and deleted
    automatically when a client of ddcmp uses the link. The port-name
    refers to the port managed by this command.
