Thanks for the advice, but so far no luck, it's compiling one last time
with a delay of 500, I also changed the code
to spit out the return value of both calls and they are both returning
with an errono 5. Is this a standard errono or
something wavelan specific. I was trying to trace back through the code
to see what exactly was failing and why.
I'll continue when I get home , again thanks for all the help.
