Sorry to not respond earlier, Niels.

Haven't heard of anything. Sorry about that. Then again, I run Linux for a reason- it isn't possible for a program to do that to me.

Hi, (Sorry, my English is not good) I would like to know if it's possible to use legOS (LNP) to get communications between RCXs without the PC, I mean, without an intermediate between the RCXs.
