This being really offtopic I guess I might as well detour you a little more:)
One painfully slow alternative might be to hook this Windows machine's
parallel port to a linux running one, get the first step of the protocol.
Implement it on the linux machine, and try to talk to the mp3 player from
the linux machine with this first step of the protocol. Get the mp3 player's
respons. Hook up the windows machine again, start the conversation, and use
the mp3's responce of the previous step, get the respons from windos, etc.
etc etc etc.
Might be easier if you have more machines hanging around,
but atleast you need 2. Doupt this is what you need:)
