Check also how you are initializing, and incrementing RxBuffer and RxCounter.
Check also how you are NUL terminating the data in RxBuffer before you use puts() or printf(). If you fail to put a NUL character at the end of the buffer you might well see junk.
Post enough of your code for others to review/build.
