Short-term
1. figure out where other serial ports are on SBC
		-which connector needed? custom?
2. fix discrete device problem in camctl.c and/or cam_ui.c
3. add logic in cam_ui.c to support:
		-zoom,focus,iris
4. add logic in both camctl.(c|h) and cam_ui.c to multiplex
 	 panning and tilting
5. figure out comm protocol with Luc, Mike
6. verify serial port interrupts in QNX (for sensor input)
7. start developing closed loop control platform
		-resource manager, thread waiting on queue, or device driver
8. test cam_ui on QNX

Medium-term
1. figure out Q_a and Q_b transforms for relative coordinate system
 translation

Long-term
2. testing, integration
