Controllling the Lego RCX2.0 directly from a laptop's ir port.

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 ?

you must close the serial port using the IR before you can use it for anything else.  

how to close it?   i don't know, im not familiar with Lego software.  how did you open it?   there should be a complimentary command to close the port if you could open it.

you could look into getting a USB/Serial adapter to give yourself a second serial port.
