Accessing raw devices (was: write alignment matters?)

But how would you achieve that?
Given your analogy to accessing terminals, you would need an equivalent of 
termcap.
Or, more reasonably, ioctls telling you the constraints (alignment, max/min 
size, size quantisation etc.) of the device in question.
