I couldn't find anything better about licence of this code snippet than
http://nion.modprobe.de/blog/archives/535-Fun-with-copyright.html
so for the delight of lawyers etc, this minimally bugfixed version here 
is free to use by anyone for anything, as far as I'm concerned.

duh, changelog:
fixed false "bad answer (02 81 08...)" for battery, mode
fixed some indentation (code formatting)

Fun with copyright

Posted by Nico Golde in 
Tuesday, April 17. 2007

Today I stumbled over the copyright file for Debian for revoco because of an RFS (request for sponsor).

To quote from http://mentors.debian.net/debian/pool/main/r/revoco/revoco_0.3-1.diff.gz

License:
In revoco.c is written, a bonobo has written the code,
so no copyright applies.

I got the following mail from the owner of the bonobo, after asking
about the licence of the code (the mail is in German, English tranlation
follows):

[...] 
English translation:

> In revoco.c it's written:
> Written November 2006 by E. Toernig's bonobo - no copyrights.
> For German law that is wrong, you have written it, 

Why do you think so? It was written by my bonobo!

> so it is your copyright.

No. If any, so of the bonobo. But because the creations of animals
are not "protected" by the copyright-laws,
it is public domain (or maybe "bonoboware?).

[...]

> Would it be possible, to put revoco under the BSD (oder GPL, LGPL) licence,
> so all the Linux-users can use it? 

My bonobo does not know anything about liences. If you want to
enter something for Debian, "public domain" would be the best.


Thanks E.Toernig, this made my morning
