Typically you cannot do that sort of thing from the command line, as without
an application the devices will remain in PREOP state, and outputs are
normally not allowed to activate until the device is in OP state.  (And even
if you use the command to explicitly request OP state, devices with outputs
will typically not remain in OP unless they're being updated cyclically by
an application.)

You will need to write an actual application in order to bring devices to OP
and keep them there.  See the examples included with the library.
