Well, the schematic says 8.7V, but I couldn't find
that so I used 8.2V too.

Ok, I think I uninstalled the WinXP/NT driver
yesterday. I installed it again, but when I choose
Direct I/O I don't get any signal on the COM port.
Delay is 1 mS. New measurements:

Ground reference is pin #12/31.
x -> y means that the measurement is first x then
starts going up/down until it reaches y.

MCLR (pin #1): 9.75V -> 8.68V (1-2 mins later) - Off:
-0.5V - Should be: 14V
Vcc (pin #11): I measured about everything below 1V
(starting at 0.95V and then it keeps getting lower) -
Off: 0.2V lower than On - Should be: 5V
Clock (pin #39): 15.7V/12V - Off: 0.2V -> -0.2V -
Should be: 5V +- 1V
Data Out (pin #40): 0.4V -> 0.15V (2 mins later) -
Off: -6V - Should be: 5V +- 0.5V

I'm getting so frustrated.
If anyone comes up with a solution or something,
please tell me :).

Thanks, Anthony
