Case 1 :

It depends on how your read hardware ( ) function is designed. A tight loop like that is not processing events, so if you function relies in any way in event processing then that system won't work. Can you post a summany code of your function an some detail on how it interacts with the hardware? Does it use serial functions or GPIB or VISA or a third party dll or what?
