These commands are low-level calls to ROM firmware. If you want to simulate
original firmware' behaviour you mast do a little coding.
May be you will be interested to see my small example at the end of this post.
This is the part of my monitor I'm using to control RCX, and it simulates look
and feel of original monitor (only "4th" instead of small man figure on
LCD ;).
BTW, when you call POWER_OFF word directly, the RCX will be really switched
off and will stay in this state until you will not press On/Off button.

I'm sorry to tell it but there were few bugs in 1.0.7 samples (so, seems also
in 1.1.0). I think it happened because button API has been changes, but few
scripts remain unchanged. Here they are:
testlight.txt, torbalall.txt, torbot.txt, tracker.txt
I'm really sorry what I was so lazy and didn't report about this on time...
Another reason - many things will not work if you will not call RCX_INIT (and
company) before. In case you have played with POWER_OFF... This word “resets”
RCX, so you need to re-init everything again. (see example below).
