I have one student who is doing voice-control of her MarkIII from her
Mac using a bluetooth link. The commands are single characters coming
in over the hardware UART port after SCP is disabled (\A). She will be
using oSerial to receive the characters but the rate will be very
slow, i.e. one character per command every couple of seconds. I
suspect that the OOPic can handle that rate without difficulty.
We have 4 weeks until the science fair and I will be very busy helping
kids debug their OOPic programs. ;-)
