Module Name:
SimpleTextOut.h
Abstract:
Simple Text Out protocol from the EFI 1.0 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 agregation
of multiple physical devices.
