When using KStars (or Cartes du Ciel) with the INDI driver for the Sky Sensor 2000 PC (lx200ss2000pc), sometimes a slew will never end, and that will cause the mount to not respond to any slew commands until the driver is stopped and restarted, or an abort command issued.
In order to solve this, I added configurable slew accuracy in INDI for RA and DEC. A value of 4 arc minutes seem to work well with my mount (Vixen GPDX).
