This command list has been generated by trial and error with S-Link equiped CD changers. Listed are all the commands we have seen generate either a coded response or some activity on the changers themselves. Commands identified as unknown generated gibberish as yet to be deciphered or some other tell-tale response. The descriptions in this list are a best guess since I don't have access to the actual specification.
All constants are in hexadecimal unless otherwise noted.
I've added notes where it seemed necessary to clarify description, or data fields. If you find a mistake or learn something new, I'd love to hear about it. I'm especially interested in experiments with devices other than CD changers. The document is now a compilation of our experiments and other web sources . A lot of the commands and responses are only supported on the later players.
