| 731 | \r |
| 732 | Converts a stream of Unicode characters from a terminal input device into EFI Keys that\r |
| 733 | can be read through the Simple Input Protocol. The table below shows the keyboard\r |
| 734 | input mappings that this function supports. If the ESC sequence listed in one of the \r |
| 735 | columns is presented, then it is translated into the coorespoding EFI Scan Code. If a\r |
| 736 | matching sequence is not found, then the raw key strokes are converted into EFI Keys.\r |
| 737 | \r |
| 738 | 2 seconds are allowed for an ESC sequence to be completed. If the ESC sequence is not \r |
| 739 | completed in 2 seconds, then the raw key strokes of the partial ESC sequence are \r |
| 740 | converted into EFI Keys.\r |
| 741 | \r |
| 742 | There is one special input sequence that will force the system to reset. \r |
