If you are running your application program, say Oscilloscope, on the machine to which the mote is attached you don't need SerialForwarder. What is happening is that SF opens the serial port when started, and then O'scope attempts to open the same port and gets the busy error.
If you really want to use SF as a middle-person then you need to change the O'scope MOTECOM setting to point to the SF network port (actually I think that may be the default so perhaps just un-setting MOTECOM will work, and no, I don't remember what the actual syntax should be but it is online....someplace). You should be able to wire DemoSensor to any ADC input and see wiggly lines if you touch the input pins.
