It occurs to me that the player will, in the final installation, be using the DC/Car mode because it will be in a sled. So car_rate=9600 will be just fine. As I'm debugging on the bench, I can force DC/Car mode for testing. So that's fine.

But now I have what I think might be another problem. I think that the player might have serial turned off or disabled by default when in DC/Car mode. Is that true? Trying to search old threads about other serial projects talked about needing to re-enable that functionality but I'm not clear on the details. Anyone have any more data about that, for example, whether that's still true in recent versions of Hijack, and what the config.ini commands are for that purpose?
