E, reply
Description:
This code defines a set of event reports (S6,F13) to be sent by the VersaPort to the Host.
First, the Host defines reports (VID list of data items) using this message. These reports
are linked to events by the LER message (S2, F35). When the event actually occurs, the
annotated report is sent (S6,F13), including all items defined in this report.
