I take it the cybermaster, radio controlled kit is not available. Is there an equivalent radio controlled program to work with the RCX? I know we have some folks here at UMaine working on such, but it seems like there used to be a solution. Any info (...) (24 years ago, 22-Jan-02, to 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 (...)
