Your serial port didn't receive any information from Mouse,
           this could be the following reasons :

           <1> There is a bad connection between mouse and serial port .

           <2> You serial card might have a wrong jumpper setting :
                 The standard setting should be the following :

                       Port #    Address    IRQ#
                     -------------------------------
                        COM1       3F8        4
                        COM2       2F8        3
                        COM3       3E8        4
                        COM4       2E8        3
                    Please double check your setting !

           <3> Your serial port might not be able to output enough voltage
               to activate mouse . This mouse requires 5 volt .
