Several of my Sony components (receiver, cassette deck, CD) allow for
some kind of interconnection to each other on their back panels, using
a thin twisted pair.  There are two connections on each, allowing a
"daisy chain".  I'd like to have my home computer (CoCo3 running OS9)
be able to control these components, and this interconnect could be
a good alternative to attaching an I/R LED to one of the CoCo's ports
and programming it to imitate the Remote Commander.

Does anyone know, or know where I can find out, the signal format
on that interconnect?  I'd also be interested, for obvious reasons,
in the signal format of the I/R signals from the remote.  Seems
likely that they'd be the same.
