Looks like this part of the documentation needs to be updated.
Try this instead:
halrun -I -f saved.hal
to start the realtime environment (halrun), load saved.hal (-f
saved.hal), then show the 'halcmd:' prompt (-I).
You'll need to issue 'start' once at the halcmd prompt to start the
realtime threads; the 'start' command isn't written by 'halcmd save'.
