Do you have a way to check the com port? You might have a bad port.

Or may be they inserted a secret timer/counter inside the programmer to terminate the life of it; and now it is time to buy a new one.
I am a great conspiracy theorist!

Sorry, I haven't checked the list in a few hours. I replaced the crystal, and checked the com port. I normally get the green light on power up whether it's hooked up to the PC or not. Does the chip do a diagnostic on the transistors on power up?

Otay... I spoke to Charles at MElabs. He told me that occasionally, the PIC252 just goes astray. About a dozen have, with no aparent cause. I ordered another chip and will update the list if this works. The board is so simple, I can't believe that it won't.
Thanks for the input,

Received the new PIC controller for the serial programmer. Fired it up, and that did the trick. Thanks for the input.
