Near the bottom of the link I gave. Is a explanation of with is sent when it wants to know its last know state and what the CM11A sent back.
Ah, after going through it again, I see that does define the data and command bytes received from the LM14A following the power-up (10 & 37) is the extended status request.
The response is the extended configuration data and command bytes (02 & 3B), which has the auto-acknowledge "standard" bit set.
Anyway, the communication through the XTB-232 agrees with the X10 documentation.
