How to get command line

I’d just suggest to use SSH / Putty.

For Beginners - How-to SSH to RPi - Setup Putty in Windows

Otherwise you could just use Raspbian Lite and install piaware: PiAware - dump1090 ADS-B integration with FlightAware - FlightAware

Anyhow you might want to just debug the issue but i thought i’d offer 2 work-arounds.
