Simplify the problem a bit. Just make the loop write a single char (I like U...) and see if you can read it in a serial program. I would consider using realTerm over putty for debugging uart issues as well. It has a lot of good features for digging down to the raw byte stream, including a nice indicator light that tells you when there are framing errors.
