UsePriorityFlag
Summary
Indicates whether this connection uses priority messaging.
With priority messaging, the device with the highest priority
sends its packet before any other devices can send theirs.
This is accomplished by assigning each priority device a time
slot where it can transmit before all other lower priority and
non-priority devices. These time slots consume network
bandwidth; therefore, priority messaging should only be used
for critical devices and data.
Availability
Local, full, and lightweight clients.
