Hello

I want to generate a 1200 baud 2 audio(1200hz, 2200hz) tone stream. But, to make 1200bps my maximum tone duration must not exceed 833.3 uSec (1s/1200).

The sound command in PBP had increment of only 12 millisecond. Is there a way to reach the 833uS ?

I want to re-create AX.25 Amateur radio Packet trame.

Thanks,
