o  change confidence

    Generated each time the transport service detects a change in the
    connection's confidence value. (The confidence value indicates
    whether the Transport layer expects a transmit operation to
    succeed.) This event suggests a change in the connectivity
    between the outbound stream and the sink.   Argument:

    confidence      New transport confidence value.

    false           It is unlikely that a transmit operation would
                    succeed under the current circumstances.

    true            It is likely that a transmit operation would
                    succeed under the current circumstances.

 o  change filter

    Generated each time that the filter for a stream is changed,
    whether it is changed by a block, ignore, or pass command
    or by using set to change the value of the catch all filter
    characteristic. The initial values of the filters for a stream
    are reported as arguments in the enable stream event. A filter
    change event is filtered according to its new values.

    Arguments: (OpenVMS)

    new catch   Specifies the current catch all filter setting.
    all filter

    new global  Specifies the current global filter setting.
    filter

    new         Specifies the current specific filter setting.
    specific
    filter

    old catch   Specifies the previous catch all filter setting.
    all filter

    old global  Specifies the previous global filter setting.
    filter

    old         Specifies the previous specific filter setting.
    specific
    filter

 o  disable

    Generated each time an outbound stream is disabled by a disable
    command.

 o  disconnect

    Generated each time a connection is closed on an outbound stream.
    The disconnect can be caused by the event dispatcher closing
    idle connections, a management command, a network failure, a sink
    crash, or a sink disconnect.  Arguments:

    disconnect   Identifies the cause of the disconnect.
    data
                 0   remote disconnect
                 2   shutdown requested (OpenVMS)
                 3   management directive

    reason       Session Control layer reason for the disconnect.

 o  enable

    Generated each time an outbound stream is enabled by an enable
    command.  Arguments:

    catch all   Value of the catch all filter when the stream is
    filter      enabled.

    global      Value of the global filter when the stream is
    filter      enabled.
    (optional)

    specific    Value of the specific filter when the stream is
    filter      enabled.
    (optional)

 o  events lost

    Generated whenever the outbound stream cannot allocate resources
    for event transmission. The event-logging function guarantees
    that this event cannot be lost. Also, you cannot block this event
    unless all events for all modules are blocked.

    This event is placed at the end of the queue. If another event
    cannot be queued because of resource limitations while this event
    is still the last event in the queue, the number argument is
    updated to reflect the latest total of lost events.  Argument:

    number      Number of consecutive events lost.

 o  shutdown

    Generated each time that a shutdown operation results in an
    orderly disconnect. You cannot block shutdown events for an
    outbound stream.

    Arguments:

    reason      cancelled    The shutdown was "neutralized" by an
                             intervening disconnect; therefore, the
                             receiver should not shut down.

                disconnect   The shutdown was caused by the
                timer        disconnect timer.

                disable      The shutdown was caused by a disable
                directive    command that specified an orderly
                             shutdown.

                shutdown     The shutdown was caused by a shutdown
                directive    command.
