At first, it seems logical that firmdl3 would be the best place to make the change. However, it was very easy to allow the Host ID to be changed at runtime. Whether changed by a user program or changed via the RCX buttons/lcd, it is easy enough to (...) (22 years ago, 24-May-02, to lugnet.robotics.rcx.legos)

It seems to me that a lot of the discussion lately has been on networking multiple IR (infrared) clients using legOS. Is the IR tower using an ID? This would identify messages from the IR vs an RCX. Also could the addressing be extended to allow IP (...) (22 years ago, 21-May-02, to lugnet.robotics.rcx.legos)
