When the GES receives a
GES Status Command
it will respond with a
GES Summary Status
packet.
The GES also supports up to two requests for 1Hz
GES Summary Status
updates. The first two
requestors will receive
GES Summary Status
messages at approximately 1Hz intervals. If a
request for 1Hz updates comes from the same IP address, but from a different port it will replace
the previous 1Hz update request.
