Miek:
Excellent, thanks, that's the result I was hoping for :)

In theory, you should be able to send back ":TEST:INSTR:INFO:DATA E4916A,JP1KD00868,010,000,000,000" (ie: just swapping the first 000 to 010) to enable the LCR option.

A few caveats:
I'm basing this on reverse engineering the v2.13 firmware linked above. It's unlikely, but your version could behave differently.
The firmware does a bunch of checks on the string sent to verify the option strings, however it does let you overwrite the model (to either "E4916A" or "E4915A") and the serial number so type carefully.
There could be side effects I haven't noticed, so it's probably best to have a backup of any flash in there for minimal risk.

Thank you very much!

Looks like this command doesn't work here, it beeps and shows "GPIB ERROR: -148" every time I send it to my E4916A.

Hmm, I guess the value might need to be in quotes, so:

--- Code: ---:TEST:INSTR:INFO:DATA "E4916A,JP1KD00868,010,000,000,000"
--- End code ---

I tried adding quotes after the first failure, unfortunately it didn't work and caused "-102 Syntax error".  :-//

Ah, OK, thanks for trying it.
I had a closer look and it seems to be treating them all as separate arguments, so quoting each individually might work:

--- Code: ---:TEST:INSTR:INFO:DATA "E4916A","JP1KD00868","010","000","000","000"
--- End code ---
