A light sensor connected to port 2 can cause on output from port 1. To see this (if you are using lejos), download the View object and hook up a light sensor to port 2. On my RCX, the port 1 raw values fluctuate between about 1010 and 1019. A (...) (22 years ago, 1-Aug-02, to lugnet.robotics.rcx)

I'm not sure who would be responsible for this but the legos website at sourceforge is broken. (URL) doesn't work. It looks some changes were underway for the brickOS name change. mark (22 years ago, 29-Jul-02, to lugnet.robotics.rcx.legos)
