This is a small utility that attempts to decode the communication between a Denon receiver and iPod dock.

For a little write-up, please visit my blog post on the topic.

The four threads that are being started in main listen to a total of four serial ports. The first two listen to RX and TX between the iPod and the dock, the other two listen to the two signal lines between dock and receiver which is why the data needs to be decoded by XOR'ing all bytes with 0x31.
