| Patch 10: This works for me under Cygwin with a USB tower, but some of the files such as rcx_comm.c have a bit of platform-specific code. Patch 11: I've noticed that the linker command file is a little different in Bibo than it was in BrickOS. If (...) (15 years ago, 21-Apr-09, to lugnet.robotics.rcx.legos)
