Hi guys,

I made the programmer with 3 resistors and using the ICPICPROG 1.0D.
I was confused with the pins connection between COM port and the PIC IC.
I connect to 16F628A as below:

TXD (Pin 3) -----[4.7K]------ MCLR/VPP ( Pin 4)

GND (Pin 5) ----------------- Vss (Pin 5)

DTR (Pin 4 ) -----[4.7K]------ RB 7 /PGD (Pin 13)

CTS (Pin 8) ----------------- RB 7 /PGD (Pin 13)

RTS (Pin 7) -----[4.7K]------ RB 6 /PGC (Pin 12)

The ICprog run fine at Windows 98SE.
Under XP Pro SP2 the program show error : Privileged Instruction...

How i can use ICprog under XP Pro?
