(...) My understanding of the IR tower issue that is being discussed here is that simply plugging the IR tower into a serial port on a machine running W2K is causing the LED to turn on and stay on continuously so long as the PC is operating. I may (...) (23 years ago, 8-May-01, to lugnet.robotics)

(...) No, just plug the IR tower into a serial port of a PC running Win2K with nothing but the desktop showing. The green LED comes on, but I'm not sure if the IR led is energizer or not... Cheers, Ralph (23 years ago, 8-May-01, to lugnet.robotics)

(...) Maybe Lego are deliberately overdriving them in an attempt to get more range - in the sure and certain knowledge that they won't be left turned on for long enough to damage them? (Erm - well - theoretically that is). (23 years ago, 8-May-01, to lugnet.robotics)

According to the schematics of John Barnes (Serial IR tower), the only way to light the green LED is to sent data or more precise, to hold the TXD line in high state.
