The CM11A X10 interface is natively supported via serial interface, no other software is needed. Most basic X10 commands are implemented. Events get generated for any command the CM11A receives from the powerline. Macro functionality is not implemented as I do not use it and do not think that it would add much to what Eventghost already offers.
The plugin automatically responds to CM11A's request to initialize after power failure. Besides X10 commands, it can also send a reset command that is helpful when the CM11A gets corrupted (which seems to happen every once in a while).
Code attached.
