Re: CONST vs. VALUE on a pointer parameter

Darren, I just wanted to make sure you knew that you need to remove the
Const from BuffLenSent too.  If you leave the Const, the parameter will
get passed by reference, and the API will try to interpret the first 4
bytes of the pointer as an integer.  Since the first four bytes of a
pointer seem to always start with x'80', the API will think you passed a
huge buffer.  The problems associated with this might not show up right
away the way they do with the pointer/const problems.
