I've had the D10, D11 and H-21. All have had the service port required  
for changing channels.

The issue you might run into is the one I'm having right now on my  
third box.. I can't find a Serial->USB converter that works. The ones  
using the pl2303 chips work correctly, but the ones using the pl2303X  
chip do not. There is no way to tell which chip it has by looking at  
it or reading a description online. I've called a couple of  
manufacturers who all tell me the "pl2303 are *long gone*". So if you  
find one that works, let me know. I only have 2 older ones that work  
and about 4 newer ones that don't (the same brand and everything).
