Trouble with RS-232 mc9s12dt256

Hey guys,  noob here.  I've been working with the mc9s12c32, and whenever i talked over RS232 i would just check the TDRE bit to indicate the transfer buffer is empty, and when it was, i would place a character in the SCIDRL register to transmit it to the screen.  Now that i have switched over to a mc9s12dt256, this code does not work (i have updated it to use sci0 registers), i set everything else the same but can't get anything to come out of hypterterminal on Windows XP

 

Any Suggestions/ideas?
