Hi,
I had tried the echo setting but nothing, I've tried every setting I can think of in H/T and still no characters show up in window.

mister-e,I'm fairly sure I have the define already in the code.I think it's something with the H/T because no matter what I do, nothing.

Does the tx line from the pc need to see a weak pull up or down or something before the typing will show up?

I'm going to go see if I can find a MAX232 chip and try that.

Thanks for your patience and help!
