Place a .1 MFD 1000V capacitor across the 240V line in the house like this:


            L1             Neutral          L2   
             |                |              |
             |                |              |
             | <--- 120V. --> | <- 120V. --> |
             |                               |
             | <----- 240V. ---------------> |
             |                               |
             |                               |
             |                       | |     |
             O-----------------------| |-----O
             |                       | |     |
             |                               |
             |                   0.1MFD      |
                                 1000VDC

You can do this without disturbing the wiring by puting the the capacitor
into a 240V plug and pluging it into a 240V outlet in your home.  

If you are experienced in working with live home wiring, use your voltmeter
to locate 240V in one of the wall boxes and connect the capacitor there.  The
bathroom wall swith may be a good place to look if it also contains a
receptical.  

The capacitor will allow the BSR control signals to pass to the other
line, so that the whole house may be controled.  It works for me.

PS:
If you'd like to have your UNIX (tm) system control your home via a BSR
"Power House" RS232 interface, you'll find a program written by Larry
Campbell in /usr3/public/bsr.c[12].Z on conexch.  This is available for
anonymous UUCP transfer.  There's a Systems/L.sys line in the .signature.
