Denys,

Thanks for your reply.  I was looking for info on how to accomplish
that same thing using POKYMODE and last night I got it working.  The
two attached files make the most sense with respect to Poky, but can
be generalize to OE if needed.

Hopefully someone will benefit from them.  I'll stop cross-posting to
the lists now ;)

Mike
