==Usage and Notes==
the interpretation and/or existence of values in each parameter in the packet is controlled by the value in the Dialog parameter. The current range is 0-42 and the various permutations are listed in the table below (a work in progress). Some of the values are obtained from packets that only appear via the EventQueueGet_CAP, but documentation of that is another "work in progress," even less further along.
 All possible interactions of Dialog byte and other packet variables
