adding/removing ntrip devices via gpsdctl?

[Michael Haberler]

I can use the built-in ntrip client when passing the ntrip URI to gpsd at 
startup - after a few seconds gpspip -r shows

        
{"class":"DEVICE","path":"ntrip://rtk2go.com:2101/stiwoll","driver":"RTCM104V3","activated":"2022-10-20T15:12:47.397Z","flags":4}

I had less luck with trying to add/remove ntrip client URI's with gpsdctl 

like starting just with a GPS device, and later adding

        gpsdctl add ntrip://rtk2go.com:2101/stiwoll 
<ntrip://rtk2go.com:2101/Gutsche>

in this case gpspipe -r shows the device was activated, but no driver was 
selected:

        
{"class":"DEVICE","path":"ntrip://rtk2go.com:2101/stiwoll","activated":"2022-10-20T15:14:57.435Z"}


is that a scenario which is supposed to work?

I'd like to get out of the network dependency for gpsd startup, and possibly 
add/remove ntrip clients through UI interaction

thanks in advance,

Michael
