Responding to: ???'s previous message
What "good reason" could motivate you inserting a resistor in the GND connection??

There isn't any!

Resistance in the supply rails            01/01/70 00:00      
   inductor instead of resistor            01/01/70 00:00      
      yes, and no and I think the theory is flawed            01/01/70 00:00      
         Spice?            01/01/70 00:00      
            That would probably help, but ...            01/01/70 00:00      
      That's what I said            01/01/70 00:00      
         Not in the gnd path!            01/01/70 00:00      
            Well ... this normally doesn't work so well, but            01/01/70 00:00      
   If this scheme is used it would also be well to...            01/01/70 00:00      
      This does increase the supply impedance            01/01/70 00:00      
         please clarify with a simple schematic            01/01/70 00:00      
            the bypass cap\'s always go between Vcc and Gnd            01/01/70 00:00      
               Which Vcc, Which gnd            01/01/70 00:00      
                  There's a cap on either side of the resistor(s)            01/01/70 00:00      
                     is it            01/01/70 00:00      
                        Not quite ...            01/01/70 00:00      
                           don't use a resistor in the GND connection            01/01/70 00:00      
                              What >good reason< could this be??            01/01/70 00:00      
                                 What good reason could this be??            01/01/70 00:00      
                                    Using a resistor in the GND connection...            01/01/70 00:00      
                              How would that come to pass?            01/01/70 00:00      
                                 Why should I insert a resistor in the GND line??            01/01/70 00:00      
                                    Seldom andonly if it is of benefit            01/01/70 00:00      
                                       No disagree, but ...            01/01/70 00:00      
                                          The regulator can't pull the Vcc down            01/01/70 00:00      
                                             This has nothing to do with imbalance!            01/01/70 00:00      
                                                Kai, I don\'t disagree ...            01/01/70 00:00      
                                                   Again, do not add any impedance in the GND line            01/01/70 00:00      
   tantalum capacitor across the MAX232 power pins            01/01/70 00:00      
      It's a matter of careful choice            01/01/70 00:00      
      Yes they does            01/01/70 00:00
