Library /sys$common/syshlp/net$mgmt_help.hlb Modem, port  *Conan The Librarian (sorry for the slow response - running on an old VAX)

    The modem connect data port entity is associated with a line and handles
    the transfer of data. Data ports are created and deleted automatically when
    a client of the Modem Connect module uses a line.  The port-name refers
    to data port managed by this command.
