    Yeah -- I know and I'm the sure the answer is yes -- was just being extra sure.

    But I'm interested in the PC itself -- not the peripheral device (PIC etc).

    Take away the hardwire and do you see a pullup voltage INSIDE the PC on
    the data pins?

    Have you looked at the data sheet of your PIC.

    nevermind -- answer is yes as I suspected.

    PIC datasheet?

    "inside the PC" -- "not the pic"
