Remarks: 
  Control of data output through “O0~O7” commands as well as setting up 
weighing scale’s functions, are actions that bring about similar effects.  
  Implementation of commands “O8 and O9" is connected with data input com-
mands. 
  If any command from the “O0~O9” range has been carried out, then its status 
will remain active until the next command is inputted. If, however, the weighing 
scale is switched off, then the output data control system will return to its pre-
vious setup.
