The Empeg will think (Correctly) that it is running on AC power, and default to 115200bps on serial. No issue with that.

The only function that cannot be convinced of AC power is the boot firmware, which will not permit serial download of a new kernel unless something is inserted into the AC power jack on the back of the player.

As discussed earlier in this thread, this is a small issue once a year or so when a new software release is made available -- in which case, just pull the unit out of the dock, install the new release, re-install Hijack, and then stick it back in to the dock for another 8-12 months (or longer).

The serial port doesn't have DTR.

Cheers!
