I have studied the sources on the WEB for LNP but have not found any examples of C or C++ code for RCX to RCX communication. I have two RCXs and would like to build something that takes advantage of 6 inputs and 6 outputs. Do you have a sample you (...) (22 years ago, 14-Jul-02, to lugnet.robotics.rcx.legos)
