1. A computer comprising:
a first computer pin,
a second computer pin,
a third computer pin, and
a hardware interface comprising:
a first hardware interface input, a second hardware interface input, a third hardware interface input, which are coupled, respectively, to the first computer pin, to the second computer pin and to the third computer pin,
the hardware interface further comprising:
a first resistor with a first first resistor pin and a second first resistor pin,
a second resistor with a first second resistor pin and a second second resistor pin,
a transistor, and
a comparator;
the first first resistor pin being coupled on the one hand to the first hardware interface pin and on the other hand to a first transistor pin;
the second first resistor pin being further coupled on the one hand to the first second resistor pin and on the other hand to a second transistor pin;
the transistor comprising a third pin;
the second second resistor pin being coupled on the one hand to the second hardware interface pin and on the other hand to a second comparator input;
the second hardware interface pin being coupled to the first hardware interface output;
the comparator further comprising a first input; and
the first comparator output being coupled to the second hardware interface output.
