I have the rs232 docs from onkyo... Has anyone used these commands?

I am having no luck out of a RFX9600... Other devices work fine..

Power on I come up with !1PWR010x0D
Communications set correctly...


Any thoughts?

Tried !1PWR010x0D0x0A as well...

Happy New Year....

!1PWR01\r That works... Hope this helps....
