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.

// pulled from the wide glyph database and will display locally as a wide character (16 X 19 versus 8 X 19)
// If bit 7 is off, the narrow glyph database will be used. This does NOT affect information that is sent to
// non-local displays (e.g. serial or LAN consoles).
