  Simple Text Out protocol from the UEFI 2.0 specification.\r
\r
  Abstraction of a very simple text based output device like VGA text mode or\r
  a serial terminal. The Simple Text Out protocol instance can represent\r
  a single hardware device or a virtual device that is an aggregation\r
  of multiple physical devices.\r
