Look here for the low level commands:

This hasn't been updated for a while, so you might want to save it some 
place.  It might go away.  There are some detailed command entries at 
that site.  You might find some better or confirming data.

Some folks download a new OS and interpreter.  Variations of Forth, 
Java and C are are popular.

I'd consider doing this in three stages.  The right way to go might be 
more obvious after tinkering.

1  Make something that sends and receives simple hex commands and test 
tethered.  (See function rcx_send in the send.c example.)

2  Make commands and functions for control and sensing.  Do some 
tethered projects with that.

3  Make a compiler from above plus program control to RCX commands.  
Download those.  Turn the robot loose.
