You don't state how you come to the conclusion that it doesn't send the
codes.  I can either assume you're experienced with X-10 devices, or that
you're a novice.  If you're the latter send me mail, we'll discuss it offline.
If you're experienced, then I assume you've plugged some other X-10 controller
into the same outlet and verified you don't have a basic problem.
Basic problems include the device you're wanting to control being on a
different 120v leg of your house wiring (fairly common problem), interference
from wireless intercom (which also uses carrier current transmission),
wrong house code selected, ....
BSR/X-10 controllers use a proprietary circuit to transmit a serial message
with pulses at the top of each AC cycle, I believe.  And I seem to have read
a technical description of the coding in the documentation included with
the CP290 PC-programmable X-10 controller, which is not with me at the moment.
