I have found that killing a task which is sending data via lnp will cause lnp to stop functioning. Turning the brick off then on again will get lnp working again. The issue is with the semaphore(s) used in the kernel tasks. Currently there is no (...) (22 years ago, 4-Sep-02, to lugnet.robotics.rcx.legos)
