RLV - is there a way to determine if it's on or off for the current user?

I have a script that sends a rotation message to the avatar  llOwnerSay("@setrot:" + (string) ang+"=1") ; 

Is there a way to only send it if RLV is enabled in the viewer?  It's harmless if it isn't enabled but it does clutter the Chat window.

Thanks

you will have some clutter no matter what you do. you can use @versionnew or @versionnum to see if there is support. if you get no response from that, at least you can skip any further attempts.

Thanks I was thinking about that but thought that there may be a different way.  The listener never gets called if RLV is not present so I set a var to FALSE and turn it to TRUE if the listener is called.  I do shut down the listener after about ten seconds to help with lag.
