Ah. See the way I read that document is that it's halcmd -f -k
and it's not clear what the '\' means. So I'm guessing there's something in the hal file loaded with a loadrt? http://linuxcnc.org/docs/2.4/html/hal_tutorial.html doesn't show polygon. It's late. I've given up searching for now. Frustrating to not find anything online.
