Jim,
I finally realized I am communicating with two different people (in
very different time zones).
I agree with your comment, 'it can not be done from userspace'. Do you

to compile ? If not, I am save my time and move on to a different
vendor....
Thanks. I am also looking at your web pages & sample code.
