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