I know you are just doing your thing, but this is so disheartening to 
read...

You should search the archives. I am almost certain I timed an SFD1001 
here a while back to respond to an earlier inquiry on the same topic.

Write your own parallel routines using the IEEE lines as conduits for 
your non IEEE protocol.
