    import processing.serial.*;

    Serial myPort;  // The serial port

    void setup() {
      // List all the available serial ports
      println(Serial.list());
      // I know that the first port in the serial list on my mac
      // is always my  Keyspan adaptor, so I open Serial.list()[0].
      // Open whatever port is the one you're using.
      myPort = new Serial(this, Serial.list()[0], 9600);
    }

    void draw() {
      while (myPort.available() > 0) {
        int inByte = myPort.read();
        println(inByte);
      }
    }
