Serial sample programs cannot be debugged
Just a warning for anyone trying the sample programs with the UNO that the programs in the Serial directory cannot be debugged. In addition once you install them you will get an error from RobotC that the Arduino is no longer visible on the com port.
Don't panic

You can get RobotC to recognize the Uno again by re-downloading the firmware.
Anyone who has messed with the serial pins digital 0 & 1 knows how they conflicts with the USB Serial port (on mega you have more Serial pins to mess with).
I wonder if we will see a SoftSerial library on RobotC anytime soon?
