Lots of good info and advice from everyone - thanks for the response.  

I had a similar experience with output to a printer once.  One of the
patterns I was sending to the bit-mapping in the printer just happened
to be a CTL-D or something very similar which had a pre-defined meaning
to the printer.  Had to explicitly check for that joker everytime from
then on.  That does get to be a pain from time to time, and it isn't
exactly intuitive to debug.
