AVR-Chat

Unfortunately I can't.  I don't have the space in this design and I
need to make it as easy as possible for the end user to make their
selection.  This limits me to a dip switch that can be switched with a
pencil or finger nail.  I can't expect them to have a screwdriver
handy.  I also don't have the room for a rotary knob.
