Apologies for butting in here :-) In this case xap-send will be an
external programme which takes a xap message as an input. I think.

There seem to be a couple of ways of thinking in this, and I seem to
be alone in thinking that I should send a message targetted at the
device - in this case the lamp, and not the CM12 - even if the lamp
cannot natively pick up xAP messages.

Others feel the message should be targetted at a xAP 'connector'
application which interfaces between xAP and X10.

Nowadays I do both.

Yes - the CM12 is the interface between the PC and the mains supply.

Not quite. You need an LM12, a Lamp Module, that the lamp plugs into
to receive the X10 signal.

I guess CM stands for Computer Module?? I'm guessing at that bit. I
have't experimented with X10 so somebody will hopefully jump in to
correct me if I'm wrong in this.
