<DIV>I am using the RPi2-3 image on a Pi3 and the RB-USB-RIM. I would like
to set Channel B to output a PL tone of 110.9 Hz. In SimpleUSB, I have set
txmixb=tone.</DIV>
<DIV>I have set the level to 500. Using an oscilloscope, I see no output
from Channel B. Where do I set the frequency and how do I enable it?</DIV>
