Re: [Hamlib-developer] rotctl connected to rotctld , Range problem min max

[Ben Z en de r. <hoo...@gm...>]

I solved this by upgrading hablib to version 4.5.4 on the Satnogs Pi
libhamlib, libhamlib-dev and libhamlib0utils, after which also
python3-hamlib needed to be updated.

Now all works great !
