OK, thanks.  I understand but we seem to be at crossed purposes. 
Probably because the wording in my question was erroneous.
This was stated.
"Appears that the last two bytes of buffer are reserved."

Should have been this.
"Appears that the last byte of the array containing the buffer is reserved."

The distinction between the containing array, named buffer, and the 
"character buffer" is important.  The character buffer has length rlen 
inside buffer.   (Meaning of r in rlen is uncertain to me.  I read it 
as readLen.) The code imposes rlen <= (BufLen-2). To my understanding 
buffer[BufLen-1] exists but is never read from or written to.  The buffer 
is not limited by 0X; no need to allow for that.

ReadText begins at line 379.
