I've sent this message to h19-people with no one replying, so
perhaps someone listening hear can help.

I just looked at Heath's RS232 controlled BSR X-10 controller.
(The X-10 system let's you turn lights and appliances on and
off through your house's AC wiring.  The Heath module let's you
do this through your computer.)

As built, it's a send-only system.  What a waste, since for 
a little extra effort, it could easily have *received* commands
from other controllers, and passed them on to your computer.
Thus, you could use the 16 digit key-pad of any regular X-10
controller as a very portable input device (the X-10 system includes
a remote ultrasonic unit).

I looked at the schematic of the Heath module (model GD-1530),
and it appears that a modification to tap the data coming over the line
might be easy.  My question:  has any one done this?

Thanks,

Steve Nahm
