The ET library is Asynchronous, In other words it only sends data when it needs to. Hence your sending application will need to generate periodic heartbeats and your receiver will need to expect them. Where if it misses too many of them then it will need to perform a graceful shutdown.

On the receiver this similar to the Arduino Debounce example http://arduino.cc/en/Tutorial/Debounce. Same concept of timing and function. Actually more like a WatchDog, in that it expects a serial receive message to update the timeout before it times out.
