Asynchronous Communication Events

[Ed Thompson]

I am trying to figure out how to deal with asynchronous serial communication
events. My main application needs to be running a control loop, while I am
also listening to the serial port for commands that affect the main loop. I
am considering one while loop for the main control loop, a separate sub-vi
with a while loop monitoring the serial port for receive commands, and a
global variable to pass the commands to the main loop. Does this sound like
the thing to do?

Thanks...Ed

Instead of a global I would use the queu to communicate between the two loops

Thanks Albert. That solves a problem clearing the global after it is read.
It that one of the Queue VIs you are refering to?

That is right, you find these vi's in the advanced palette under synchronization/queues
