  Set the logging configuration as tmin:tmax:dmin:dmax.
  Here tmin and tmax are in seconds, and dmin and dmax in meters.
  With dt = time since last log, dx = distance since last log,
  and v the current speed, the device logs if

<para>
   (dt > tmin and dx >= dmin and v >= vmin) or dt > tmax or dx > dmax or v > vmax
</para>
<para>
   If you use this option, vmin is fixed at 0 and vmax at 65535 km/h.

   Example. Set the device to log every 6 seconds (or 10km, whichever
