That's an eternity to a computer.
Ok, I would recommend you read up on the Event Structure. That way you can send the data to your Arduino when you specifically command it. You can also use it to watch for a stop button press to stop you program. For the reading of your port, I would recommend setting the timeout of the event structure to something like 100ms. Inside of the timeout case, you check the time since you last did a read (use the Elapsed Time function in the Express palette). If a minute has passed, do the VISA Read.
