Actually the other way around. About every second a heartbeat is sent from the robot to the pc. The robot sends it to tell me the system is still up and running. Using that heartbeat can come in handy if a few situations, but for now, I just want to send a response that everything was send correctly. I will be on my gtalk account. Add me and we can discuss it. I will prepare some documents/diagrams to help describe things better. BR, Jason
