I understand, that you are making experience etc, that's ok. But exit(0) as
a reboot on PIC is like getting out of your car in the real life. Try to do
that while you are making 70 miles an hour! (DON'T) That's exactly what
happens on your PIC when you just do an exit(0) without properly stopping
what you are doing -- for example with the UART...
