18Fxxx Tutorial

Hello Shane,

Saw your bootloader page on Sunday, wired the max232 circuit Monday morning at 09:00 AM and had downloaded my first program into an 'F876 by 09:15!!! By the end of the day, I came to realize that this is by far one of the best time savers I've come across in the last 5 years!
Thanks for an extremely detailed description and once again, thank you for making Petr Kolomaznik's small and powerful bootloader available.
