    Check your power. Make sure that the Propeller is receiving it. Make sure that the serial terminal is disabled while trying to download.

    Are you using the Parallax Terminal or hyperterm? You have to disconnect first. and then program.

    It's Only A Stupid Question If You Have Not Googled It First!!

    OK. so Parallax Serial Terminal must be disabled when F10/F11 is pressed, and then as fast as you possibly can, you page over to Parallax Serial Terminal and click Enable. Surely there's an easier way than this. if its a short program, you might not get to Parallax Serial Terminal in time!

    Sure. Add a six second delay in your code. That's just the right amount of time to download, find the terminal, and click enable.
