    Default Data from PIC works...data to PIC doesn't

    Darrel,
    Everything compiles/assembles/programs in my EasyPic6 configuration with 18F4550 (8 MHz crystal), and it does run with Steve's VB6 GUI, but only for data from the PIC....data to PIC side of the GUI doesn't work. I double checked that I didn't have anytheng on the EasyPic6 connected to the pins you are using. See attached screen snapshot of the VB6 GUI that shows what is working and what isn't.

    I also notice that when I remove the comments on the DEFINE statements for the status LEDs that they do not light during the PLUGGED, TX or RX actions are supposedly taking place that they are suppose to indicate.

    I looked at your code and I couldn't see where the problem is. Any ideas??
