Notification events.
VSE defines a group of notification events that can be passed to a verification script for
evaluation or for retrieving and displaying some contained information. The information about the type
of event can be seen in in.TraceEvent. Please refer to the topic “Sending functions” in this manual for
details about how to send events in scripts. The notification events are not the same as packets – they
basically indicate that something changed in current stream of evaluated data.
The table below shows current list of packet events and value of in.TraceEvent:
Notification event in.TraceEvent
Physical link woke up from silence _EVNT_CONNECT
Physical link came to silence (no physical signal) _EVNT_DISCONNECT
Changing of Opcode in series of link packets _EVNT_LINKSTATE_CHANGE
