Great, thxs for this info :)

Yes, that's to be expected, from what I experienced with my MicroScout
tests.

hmmmm... let's hope someone can do some work around that :)

Yes, like I did on a CyberMaster and on a RCX.
The problem is that, doing a "custom" VLL input routine (with standard
firmware) takes a bit of CPU cycles and a lot of precious RAM and it's
impossible (I tryed various ways to do it but no can do) to read pure VLL at
*VLL speed*.
I succeeded doing a 10 to 8 times slower versions of VLL input.
That was the best I could do with stardard firmware.
(if someone has a solution to this, please post it, please ! :)
I've never tryed doing a BrickOS VLL input routine because my objective was
to run it either on a Cybermaster or on a RCX. That's the only way I could
put the two "talking". ...and the Cybermaster is stuck with standard
firmware, so, I never got to try alternative firmware on my RCX too.
Anyway, thxs for this info (and the Spy<->RCX post too) Mark :)

| After doing a little more sleuthing, I was able to find out how to process incoming IR and VLL messages. And yes, thankfully, VLL decode is built into the firmware!
