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

    Pushing the CONTINUE button resets the catchall, specific, and global
    filters to the default value for the specified Event Dispatcher Sink
    entity. It causes these filters to be reset to the values they
    had when the entity was created. It is equivalent to setting the
    values for these filters to their defaults.

    Pushing the CANCEL button dismisses the window, and no reset action
    is taken.
