I think if John had a device to test for every code request that came his way he would have a warehouse full. I am afraid he can not do any more than the rest of us unless Sharp hires him to design their code sets!

I have been quietly working on this as well. I have some documentation coming to me this week that may or may not be new. My problem is that I rarely have a set in hand long enough to do extensive testing. All I can do is look at the device and function variations.
