Heh...

you need to ASSUME, that when THRE gets generated, that you can stuff 
up to 16-bytes into that FIFO.

Actually, my experience has shown that this is a pretty good 
assumption.

Unfortunately, if you work under non-interrupt mode, this means you 
need to wait for the queue to completely drain before you can feel 
'safe' in stuffing more bytes into the queue....

not the most efficient means to go in non-interrupt mode.
