More notes:

4. Forget about using debug with interupt routines. They only 
work in real time.

5. Version 7.2 implements HSERIN and HSEROUT which are 
code blocks that use the hardware UART. In theory, they should 
take care of interupt processing for us. But direct register use 
may still needed for byte by byte message parsing, the HSERIN 
routine may add enough overhead so it can't handle MIDI data 
rates.

6. To use HSERIN you also have to enable it and use the 
SERSETUP command to initialize the UART.
