It's worth checking the comments that people posted on your 7th blog. There are ways to verify if serial communication is working. Look at Jon's and mcb's posts in particular.

You can use a loopback to read back what you are sending.

If that works, it's up to checking if it's related to the 3V / 5 conversion ...
