/* These boxconfigs have caused problems in the past.

* ** MIDI IN can only be configured on one box **
* ICE1712_STDSP24_BOX_MIDI1 needs to be set for that box.
* Tests on a ADAC2000 box suggest the box config flags do not
* work as would be expected, and the inputs are crossed.
* Setting ICE1712_STDSP24_BOX_MIDI1 and ICE1712_STDSP24_BOX_MIDI2
* on the same box connects MIDI-In to both 401 uarts; both outputs
* are then active on all boxes.
* The default config here sets up everything on the first box.
