/** @file
  Simple Text Out protocol from the UEFI 2.0 specification.

  Abstraction of a very simple text based output device like VGA text mode or
  a serial terminal. The Simple Text Out protocol instance can represent
  a single hardware device or a virtual device that is an aggregation
  of multiple physical devices.
