Not yet. Only Escient servers sporting the well-documented Escient Control Protocol as supplied with firmware version 4.1.7.2 of the Escient products.

Now, if you want to program your media server to look like an Escient and operate according to the Escient protocol, you can make it work with a 9600. I have my own home-brew media server that I implemented the Escient protocol for it and have my TSU9600 talking to my media server as if it were indeed an Escient.
