the reason this is important to me is that I'm using #defines to determine limits (bytes) of functions and such. I need to have the representive byte converted to ASCII dynamically since the operating function code wouldn't make sense in an "all ascii" format. Unfortunately the device requires an ascii packet string to perform its primary functions.

Plus all the documentation is byte driven, so it has to be converted to be "usable".

From your other response, I thought the the toascii "should" convert the byte just a the tolower and toupper function.....hmmmm.

Thanks for the productive feedback.
