Set a timer event on one of your widgets of a reasonable length, say 1
or 2 seconds. In your event handler for that widget, poll the serial
port when the timer event fires, update your application data structure
and draw. IDL timers are single shot so remember to set another timer
event at the bottom of your polling routine.
