(...) The one-byte messages supported by the RCX are not generally designed to go from the RCX to the PC. They are intended to go from the PC to the RCX, or from one RCX to another. One reason for this is that the original RS-232 IR tower would not (...) (21 years ago, 22-May-03, to lugnet.robotics.rcx)
