The problem seems to be on the Rx path.  If I 'cat' a file, it's 
transmitted without hesitation.  But when I paste in this Simpsons quote 
into the serial console via X:

-----
Mr. Burns: A lifetime of working with nuclear power has left me with a healthy green glow... and left me as impotent as a Nevada boxing commissioner.

... everything up to the end of "boxing" is echoed immediately, and then 
"commissioner." stutters its way across the screen over the next five 
seconds.
