I've done some searches, but I don't see any mention of this problem. Has anyone else noticed that fast forward and rewind don't work from the serial interface? I'm sending f<LF> or b<LF> very quickly, the little icon for FF or Rew turns on, but it just makes a sort of skipping sound while playing the normal speed and direction. This is not a VBRE file and FF and Rew work fine from the IR remote.

Also, the "backtick" radio preset store command either doesn't work or I can't figure out how to use it (as before, the IR remote works fine).

It is docked and running at 4800 baud, but I believe the problem still happens even at 115200. I'm using the latest version of the developer's image, but I seem to recall it happening with the consumer image also.

Enough people have controlled these from their PCs and their own projects that someone must have experienced this, right?
