bit banging program touble              01/01/70 00:00
   why?              01/01/70 00:00
      i need a second serial port              01/01/70 00:00
         something like this , without any warranty :              01/01/70 00:00
         a good start would be ...              01/01/70 00:00
            only 3 'U's are commingout of 100              01/01/70 00:00
               Separate the characters and look with scope              01/01/70 00:00
                  finally it worked              01/01/70 00:00

   Someday you will learn...              01/01/70 00:00
      this isnt the actual code              01/01/70 00:00
         Well then another lesson to learn...              01/01/70 00:00
