</div>Typically you cannot do that sort of thing from the command line, as without<br>
an application the devices will remain in PREOP state, and outputs are<br>
normally not allowed to activate until the device is in OP state. (And even<br>
if you use the command to explicitly request OP state, devices with outputs<br>
will typically not remain in OP unless they're being updated cyclically by<br>
an application.)<br>
<br>
You will need to write an actual application in order to bring devices to OP<br>
and keep them there. See the examples included with the library.<br>
