What I implemented now is to recognize whether the scope is already stopped and decide from that. We don't have the capability to completely configure the thing anyway, so may as well take some hints from how the user has set up the device. Complete configurability should wait for the LibreVISA version, there are just so many options I don't think it's worth implementing everything twice.

NIVISA should come with a nifty tool called "nispy.exe" or similar - it does what the name suggests. No such luck for the DS2000 series, Rigol doesn't have a Windows software for these. > It would be nice if sigrok could also support this sort of "live" > operation, where the only thing we know about the timing of the data is > that it's recent and should be displayed immediately.

Would what I explained above, i.e. using the state of the scope when recognizing the device (or maybe when starting the capture, makes a difference for pulseview?) be OK?
