By initiating a Start Host Notification, utilizing pause to wait for each screen update, then checking screen contents to monitor progress, an efficient means of monitoring screen transitions is implemented without wasteful polling.
Note: for each WHLLPSCHANGED return for pause, be sure to use the Query Host Update call in order to reset internal tracking counters.
See differences section for FlyHLLAPI unique aspect of Pause.
