You cannot program them independantly, but you can make sure your programs respond to different IR messages during normal operation. All RCX's will receive the messages, but as long as only one responds with some action then independant control is (...) (24 years ago, 22-Jan-02, to lugnet.robotics.rcx, lugnet.robotics)

Hi, It looks like you really meant a single "byte". To my understanding from the RCX 2.0 (with usb port) SDK available from Lego, the "byte" would have to be wrapped up in a certain way, such as leading sync bytes plus a number of conditions to form (...)
