Hi Kypros,

Thanks for the HIGH / LOW tip...

I've been playing around with the code some more and found that it is even better to use the FLOW pin option.. ie

SERIN2 SDI\FLOW,16780,[char]

and scrap the HIGH , LOW flow commands all together.

Its possible that the PC's UART buffe is still causing me some problems and headaches....

I may need to re wire and use the USART after all.... I will post here if I have any success.
