Example c code for binary command on xbee pro xsc sb3

Is there some example code for executing a binary command on an xbee 900 pro xsc sb3? I’ve run out of ideas. Mr code seems correct and I’m pulling the cmd pin high as specified. I get no reply; the command is ignored.
I’m using an arduino mega on an xbee explorer (regulated) adapter.

Digi does not offer Sample code for that function.
