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