Thanks for this I had a look and it could have saved me a few hours - will definitely remember it now.
I have another question in my quest for user select ability :is there some were I can read up on what the PBP command HSER_EVEN does?
I have set it up now for 8 and 9 bit operation but as soon as I add HSER_EVEN or ODD even in if commands every thing stops it is as if a define is processed no matter what.

Any thoughts on this
