For now my goal is to test if interrupts will work every time there is data in the communication line.

I would bet they don't givin' your use of ON INTERRUPT. Why did you elect not to use Darrel's instant Interrupts? On Interrupt will cause lost characters (I am betting) if it works at all. Assembly interrupts handle the event immediatly, on interrupt has to finish what it's doing before servicing the interrupt.
