Which PIC? For 12 and 14 bit cores your options are limited bececause the
stack is not accessible, so you can either do
- cooperative multitasking from the 'main loop' (not from within a call)
- Ubicom virtual-peripheral-style multitasking

AFAIK the high-end PICs have an accessible stack, so you can apply any
mutitasking technique you like.
