So the correct way is to use iecset's mnemonic mode (e.g. do iecset -c iec958:CARD=Device,DEV=0 copyright false original true) and then read back the binary values with iecset -x? I have noticed that iecset -x's output indeed changes when I do changes with iecset foo bar, did I guess that behavior correctly?
