Peter:
This is probably good news to find the bug then.. All ports should act the same, they all use the same code, they just loop through it 4 times
with a pointer to different port structures. Ive turned on pin2-9 as inputs on mine, and I can toggle the pins all day without seeing them mirror
on the upper pins. Im still a bit lost in finding this one, but Im still running tests. Peter, if the port#2 is unplugged from your computer, do the
ports2 pins still look mirrored in condition? I know you cant toggle them, but do they show a mirror of the pins as they just sit there unplugged?
