Bad expectation.  gpsd tries to do minimal reconfiguration of the
client GPS.  Checning from NMEA to native binary, and back, is the
job of gpsctl.  But I have seen reports of that mode switch is flakey.

No need to wait.  u-block is happy mixing NMEA and native binary on both
the input and output.

Correct.  I'm working on it, but nothing to show yet.

So far, the gpsd policy has been to let the user set up those
things as they wish, then start gpsd with -b.
