-/*++
- Routine Description:
-
- Converts a stream of Unicode characters from a terminal input device into EFI Keys that
- can be read through the Simple Input Protocol. The table below shows the keyboard
- input mappings that this function supports. If the ESC sequence listed in one of the
- columns is presented, then it is translated into the coorespoding EFI Scan Code. If a
- matching sequence is not found, then the raw key strokes are converted into EFI Keys.
-
- 2 seconds are allowed for an ESC sequence to be completed. If the ESC sequence is not
- completed in 2 seconds, then the raw key strokes of the partial ESC sequence are
- converted into EFI Keys.
-
- There is one special input sequence that will force the system to reset.
- This is ESC R ESC r ESC R.
-
- Arguments:
-
- TerminaDevice : The terminal device to use to translate raw input into EFI Keys
-
- Returns:
-
- None
