(...) The only IrCOMM I know of is part of the IrDA standard. It provides something that looks just like a typical serial port to the application, but underneath is layered on top of IrLAP (packet based link level prototocol for IrDA). This means (...)

I have written a tiny messaging package for lejos. What I'm having trouble with is where to put it and it's class files so that I can use it in my lejos programs just like one of the lejos classes/packages. Currently I have to place a copy of my (...) (25 years ago, 29-May-01, to lugnet.robotics.rcx)

(...) This isn't true at all. The tower converts an RS-232 serial transmission directly into IR and vice-versa. It is a pretty standard protocol. -Kekoa (25 years ago, 26-May-01, to lugnet.robotics.rcx, lugnet.robotics, lugnet.off-topic.geek)

(...) You can't really do what you are trying to do. The tower is designed to operate in request-reply mode. It sends a request, waits a few seconds, receives a reply during that time, then turns off. The idle state of the tower is off, and (...)

Even more interesting.... I've also just replaced the IRED I replaced a few hours ago in my RCX :-( This time, I'm putting a limiting resistor between the IREDs in the RCX to keep the current within limits. The following is pure conjecture on my (...) (25 years ago, 26-May-01, to lugnet.robotics.rcx)

(...) Actually, there's a regulator on the Tower that takes the voltage for the digital side to +5 and keeps it there. The capacitor is only rated for 10V. The higher voltage will allow higher current through the IREDs as they are connected right to (...) (25 years ago, 26-May-01, to lugnet.robotics.rcx)
