| (...) Hmmmm, that is a challange, because any cursory example leaves out the physics. I was just thinking perhaps if you likend polarity to a visual of a two lane highway. Trafic going in opposite directions. Flow and return. On the surface, (...) (20 years ago, 9-Nov-05, to lugnet.robotics.rcx.robolab)

Having a task repeatedly transmit a simple message endlessly means that the RCX can't recieve normal messages, possibly (...)
