Thanks, Slacker. I had already seen that and to an extent it&#39;s how I managed to stumble across the solution (if I can call it that) in the first place.

The problem (for me) is that I don&#39;t understand what is going on. I don&#39;t actually understand what this line does:

alt_irq_register( UART_0_IRQ, Flags, UART_RxD_Int);

I don&#39;t understand why it makes the Flags variable work and I don&#39;t get why ByteRec works when it&#39;s not referenced in the interrupt set-up in the same way. Also, The above line gives me that warning. What does that warning actually mean? Could it potentially be a problem?
