The AUSART uses TRUE format only (idles high). You have hyperterminal set for INVERTED (idles low). I believe your options are:

a) use the USART with a level converter like the MAX232 between your pin and the PC.
b) use software inverted serial routines (like serin/serout) instead of the USART - then you can stay directly connected to the PC.
