[arm-allstar] using command line to play available CT= for demo

cop 48 only works across USB, I think. But anyway, try something like 
this. The following generates two separate tones.

9551=cop,48,!654/250,!523/250
And here's an example that generates a sequence of 3x2 tones.

9552=cop,48,!654+523/125,!523+392/125,!523+784/250
As you can see, this is very different from app.rpt/s CT format.
