I think remote control can be divided two parts: 1. defatk mode, if you user doesn't provide remote handler, the default hanlder will be called, key M1-M3 send standard message 1-3, A1-C1/A2-C2 increase/decrease 1 outport port a-c, P1-P5 run program (...)

legOS has two download programs, firmdl3.exe for kernel, and dll.exe for user program, you can check source files /legOS/util/firmdl/rcx_comm.c and /legOS/util/dll-src/loader.c. You can find LNP in file /legOS/kernel/lnp.c and lnp-logical.c. Br (...) (23 years ago, 3-Sep-01, to lugnet.robotics.rcx.legos)

Hi, I'm a developer for leJOS (a Java VM on the RCX) and I am interested in how legos applications are transfered from the PC to the RCX (basically because the leJOS mechanism seems to be fairly flakey and I'd rather not try to implement an entire (...)

If you downloaded leJOS 1.0.2.RC6 you should download and install 1.0.2.RC8 instead as there is a bug in RC6 that causes the RCX to ignore sensors and buttons for several minutes. Apologies for the inconvenience - Paul Andrews. (23 years ago, 2-Sep-01, to lugnet.robotics.rcx.java)

She used the (...) (23 years ago, 1-Sep-01, to lugnet.robotics.rcx)
