I recently bought a surplus GE Homeminder system which controls BSR X-10
modules.  The system hooks up a television, uses a remote control to program
times for turn on/off and gives a graphical representation on-screen of the
state of each device.  It also has a telephone connection to control modules
and leave messages from remote.

Everthing appears to work (video, telephone, memos, programming) but the
x-10 codes don't seem to be transmitted.  I have examined all the solder
joints and checked the optos and transistors on the power board but to no
avail.  I am figuring since the cpu is working fine, it is an interface
problem.

Is the any documentation available on the BSR/X-10 interface that I could
use to understand how the Homeminder is sending out the codes on the AC
line?  I have my own ideas but if it is available somewhere I could sure
use the help.
