What are the different output parameters of the gsmctl -K command? The help command isn't helpful at all and I couldn't find an explanation online.

If I have an output like this 

+QENG: "servingcell","LIMSRV","WCDMA",262,01,19D3,65898,10836,477,1,-64,-3,-,-,-,-,-

I have no Idea what most outputs are. My guesses are that WCDMA is the connection type, -64 is the gsm signal strength and -3 is the EC/IO but what are the other values? The empty parts at the end are probably related to LTE I guess because I don't have a LTE connection with that output.
