Aha ! You did not tell us that either :-)

In general, I think it's much easier to debug USART code if you
use some *external* device (such as a terminal emulator on a PC,
or a RS232 line-listner).

Are you sure you get anything at all on the line connecting Tx and Rx ?
Have you checked with an o-scope ?
The blinking LED just says that your code *thinks* that it is sending
something...
