Hi think you can take a read on X-10 protocol, this one is used in home
application to send digital
signal through the power line.

If aI can remember right Marmitek have some power modem, then a modem wich
through a serial cable
conected to the PC is able to inject our signal into the power line. At the
other end simply put another power modem to retrieve the data signal.

Hope this may be useful for you.

Bye
Fabio
