It's a new year and now you have a new version of brickOS. Yes, you read that right... a new version and a first version of lnpd for Linux that works with this new version of BrickOS. Along with this lnpd support, this BrickOS now supports USB IR (...) (20 years ago, 18-Jan-05, to lugnet.robotics.rcx.legos)

Folks, I've been fiddling around with how BricxCC and NQC talk to the RCX when using the USB tower. It's because of several users experiencing problems when trying to download programs from within BricxCC (using NQC behind the scenes). Depending on (...)
