Thanks for the various replys on this and I will try them.

It may seem like angst over an external pin, BUT I have made one product 
(with motorola chip) which used an external pin to force it into boot 
loader mode. I had one customer who kept sending units back for repair 
as someone in his organisation had a misswired serial lead!!!!!

His fault, BUT who gets the blame for an unreliable product.

I never had that problems with another product with software activated 
flashing code.

Thanks

Owen
