Lpc2000

Three things to try.

1) Check your code is running at all can you flash a LED or are you
still in Boot Selector mode when you think you are running your code.

2) You have closed your Philips Flash Unitily before connecting with
Hyperterninal.

3) Try writing bytes to the U0THR, if you enable the fifo you can
write upto 16 in one go without checking if the UART is busy.

Good Luck.
