I kinda like the idea of morse in a wearable kinda... at least in your car.. if you can whistle good. first do an init string of alternating tones, 4 of each, then use the same tones to shoot out morse, or binary, to change station, etc. not very efficient for data entry, but sounds like James Bond, and you should at least impress someone with it. use the upper tone for short, bottom for long, break in between consecutive. play back could be cheesy synthesis, I have a board for an Apple ][ for that. entry could be morse if you have space constraints....for other than car, or even the car app. Bryan In article <36471632.156E@geocities.com>, Michael D.
