Tom noticed that two trhs are bad on rim.

They are reporting wacky temps and RH:

Was able to get the 40m TRH to reset and start reporting believable data by sending ctrl-R from rserial as shown above.

That did not work for the 20m TRH (which we've seen before). Power cycling port 15 with eio also does not work
