    I think I've found another side effect of using internal pullups...

    I always figured if I couldn't get any other method working for this, I'd fallback to serial/uart communications...

    I can't get the UART working

    I'm using a usb>serial chip, but it's no real matter because both pins 7(RB1/RX) and 8(RB2/TX) are always high

    Any ideas how I can get this working?
