Hello. I want to directly control a RCX2.0 from the ir port on a laptop running windows. I know I can use the Spirit.ocx to do so by means of the tower, but I know it can be done without it since the palm can do it with the pbrick library. I've extracted the code from there but I can't access the ir serial port when I call CreateFile, I suppose it's because windows is using it to scan for ir signals. Must i first stop windows from using the ir port ? If so, how do I do that ?
