I have a Denon DVD-5900. This device is not listed as compatible with serial control. I can control it via IR. My question is… I would like to control it via serial as a custom device. Is there any way to easily do this by somehow obtaining the IR control set and converting it to serial? I did try the Denon blue-ray serial driver and it does not work. I guess it’s worth a question here. Or, if anyone did write a custom device for this unit perhaps they can share?
