+ Note that not all code which meets some of these criteria is wired through

+ baud rate and transmission options can often be wired to SoftwareInit.
+ They are encapsulated abstractions which will not be invoked or

  Components whose initialization does not directly depend on hardware
  resources SHOULD wire to MainC.SoftwareInit. If a component requires a
