EngineSetLocked is a simple flag-setter, like EngineSetOutput, etc.


CommonGetLayers retrieves a summary of the entire layer list:

command: *B1#
result: 12 bytes per layer, for all layers (in mix order):

en id fl cl cl cs fd rf rf hd rh rh

en    - engine inum (internal engine number)
id    - layer id
fl    - layer flags (same as in EngineConfigure)
cl cl - current cuelist
cs    - current cuestep
fd    - current fade time (encoded)
rf rf - remaining fade time (in frames)
hd    - current hold time (encoded)
rh rh - remaining hold time (in frames)

The encoding for fd and hd can be found in the LC+ Reference.

The inum is used to be able to refer to a layer in a robust way, unlike 
the layer id which can be changed, and which it might not even have.  
You can use an inum instead of a layer id in any engine/layer command.


The remaining commands aren't really relevant, they're just for things 
like configuring IP settings etc.  You're unlikely to have any need to 
do that manually rather than using LCedit+.
