(...) I'd say this is the way to leave it, since it seems to be how you meant it in the first place. It's just very annoying to take out the batteries if ON/OFF is pressed by mistake while something is running. (...) Don't know, I've never used (...)

I tried using lnp_logical_write(), but 'cu -l /dev/ttyS0' doesn't show any (...) (25 years ago, 27-Oct-99, to lugnet.robotics.rcx.legos)
