Responding to: ???'s previous message
You see whatever I type in the terminal is echoed back. Same circuit only difference is that I installed a real max232 (genuine).

   Ha, ha, the capacitors are too big!            01/01/70 00:00      
      maybe they're too small ...            01/01/70 00:00      
      no caps are not too big            01/01/70 00:00      
         did you verify the output voltages?            01/01/70 00:00      
   They were a good deal...            01/01/70 00:00      
      yes, I learned            01/01/70 00:00      
   here is a simple log            01/01/70 00:00

      Never mind the logs...            01/01/70 00:00

               There's really no need            01/01/70 00:00      
                  Can it?            01/01/70 00:00      
                     Volt meter is good but for rough testing            01/01/70 00:00      
                        It could be a bad circuit?            01/01/70 00:00      
                           Sometimes totally untested chips            01/01/70 00:00      
                              the easiest thing to steal ...            01/01/70 00:00      
                     agreed, but ...            01/01/70 00:00      
                        Lots of things happens when packaging stolen silicon            01/01/70 00:00      
                           ripple, maybe, but proper voltages, never!            01/01/70 00:00      
                        where would excessive ripple originate?            01/01/70 00:00      
                           are we identifying counterfeits or solving other problems?            01/01/70 00:00      
                              not so            01/01/70 00:00      
                                 maybe, but not an obsolete part ...            01/01/70 00:00      
                                    Especially for obsolete parts!            01/01/70 00:00      
                                       The MAX232 was replaced by MAX232A            01/01/70 00:00      
                                          Lots have already happened            01/01/70 00:00      
                                             maybe ...            01/01/70 00:00      
                                    nope            01/01/70 00:00      
                                       Really? Why?            01/01/70 00:00      
                                          you have often advocated            01/01/70 00:00      
                                             In case you haven't noticed ...            01/01/70 00:00      
   some testing results            01/01/70 00:00      
      looks like ...            01/01/70 00:00      
         or they are from the garbage            01/01/70 00:00      
            Voltages?            01/01/70 00:00      
               yes the voltage was 7.79V            01/01/70 00:00      
                  Can't use volt meter            01/01/70 00:00      
            I doubt MAXIM would allow garbage out the door.            01/01/70 00:00      
            Counterfeit Maxim parts            01/01/70 00:00      
               How much profit could they have made?            01/01/70 00:00      
                  Profit?            01/01/70 00:00      
                     Labor isn't the critical factor here, is it?            01/01/70 00:00      
                        profit/motives            01/01/70 00:00
