AFAIK there is no way to receive Lego-Messages, except by editing lnp.c and adding
that by hand. The only Lego-Messages that brickos knows of, are those from the
remote control and the "send message" opcode (0xf7). It may be worthwhile to add
general LEGO-Message support to lnp.c together with an lnp_lego_handler...
However, I wonder why your brickOS RCX doesn't indicate that it receives a message.
