            The switches are a binary representation of the hexadecimal
            memory addresses. SW1/7 is the Most Significant Bit and
            switch SW1/1 is the Least Significant Bit. The switches have
            the following hexadecimal values: SW1/7=200h, SW1/6=100h,
            SW1/5=80h, SW1/4=40h, SW1/3=20h, SW1/2=10h, SW1/1=8h. Turn
            off the switches and add the values of the switches that are
            off to obtain the correct COM port address. (Off=1, On=0)
