We are using an event structure to control a robot. As you see in the included example, we are using the serial port to transmit data to the robot (actually hyper terminal for now). NOw that the last event has been added (including the graph at lower right), the VI stops responding and must be aborted whenever a button is pressed more than twice in a row. Perhaps the problem is that the serial port is getting overwhelmed (though we are only sending 4 bytes on each button click).
The graph event is taken from the vi called "Draw Graph With Events" that is included with labVIEW. However, instead of drawing on the graph, we send the coordinates to the robot. When the user clicks on the graph first, it works as intended, but then the
buttons don't work and vice versa.
Thanks for any help you can give.
