But from my reading of Nathans post, he is expecting something that will no=
t happen, he is not looking at the flags. This is because of the nomenclatu=
re used in the datasheet or family reference manual.

Nathan, when it says that the TXReg is cleared, it doesn't mean that the da=
ta you loaded into it is turned into zero bits, which is what you are testi=
ng for in your code. It means that the data has been transferred to the shi=
ft register, and so you are now clear to load the next data into TXREG. As =
someone else mentioned the correct way to test is to look at the TXIF bit i=
n the status register.
