Hi, if I am not wrong, I have a problem similar to Martin's: When I load the legOS-0.2.2 kernel to the RCX, the kernel dies leaving "on -" on the LCD. It doesn't accept any key input, only removing the batteries helps. When I nevertheless try to (...) (25 years ago, 14-Nov-99, to lugnet.robotics.rcx.legos)

Hi Pavel, check out the program loader. Basically, you have to register your own port handler for incoming packets on the PC. You should also acknowledge them in some way, so the RCX knows what's going on. Maybe IR networking should become secure. (...) (25 years ago, 11-Nov-99, to lugnet.robotics.rcx.legos)

Apparently, standard gcc include files are processed as well. This should never happen, as legOS defines everything on its own.

I'm afraid these are the same errors that were reported with 0.2.1.
