Yes, the Off() does a shortcircuit simulating a ON state from a TouchSensor
point of view. The Float() does the oposite, getting a OFF state this way.

I'm using NQC, because all this has to run on a CyberMaster, with it's
fixed standard firmware. This way, any CM or RCX can do VLL output, and
*hopefully* any CM, RCX and Scout could do VLL input.
I will release my MCommsLib of course, as soon as it is 100% like I want it
to be. Until now, I've done nothing others haven't done already... hmmm...
well, I've done the direct electric connection routines and the VLL output
based on a pre-calculated table of VLL codes (checksum+data) er... and
that's about the only things I think are new to this subject.
If you want an already done NQC VLL *output only* lib, you can use the one
done by Shigeru Makino (mac@research.co.jp)
http://www.research.co.jp/MindStorms/vll/libvll.nqc
Anyway, like I said above, my lib uses tables that look something like this:
