you won't be able to use LNP - those packets are completely different
from the Lego firmware ones. You'll need to write bytes directly to the
serial port (I'm not sure what support there is for this in legOS since
once you start munging the UART you probably won't be able to dll
something new). UART should be configured as 2400bps, 8 data bits, odd
parity, 1 stop bit for LEGO packets.

Probably won't help - there's one chapter on how you could use
communication between RCXs or from computer to RCX, but its mostly about
how to program the robot in NQC. No technical details on the packet
format etc.
