  A different issue is whether it's OK to output the PPS messages only at
  -D2. Should they be visible at any debug level?

I'm not clear on the strategy for what's at what level.  I would think
the first debug level would be expected to output things at startup and
once steady state was reached not print anything.  So 2 seems ok.

I would like it to be clear whether gpsd thinks the rising edge (assert)
or falling edge is the right one.  I have found that the GR601-W seems
to use the falling edge (as in the signal is asserted 100 ms after a
second and deasserted as the second happens).
