Receiver doesn't know what hit him..

So the software development continues. I finished writing the service that let's any other software module in the system to command the Pioneer VSX9120 receiver. This model includes a serial interface and the Pioneer engineers were nice enough to document the command protocol and place it on their website. The module that I wrote will allow the control of volume, listening mode settings and radio tuner. The receiver provides audio output to the home theatre set up but also the whole house audio installation for listening to music, radio or for the central computer system to notify me of anything, like incoming phone calls, emails, or whatever.... When listening to music or radio, I can control the volume from any touchscreen in the house. The automation system can have control of the receiver as well. I can have the communication module lower the volume of music playback so I can answer a phone call, for example.
