This vi has its origin from BusyBox tiny vi. But there are some differences:
The program is resident. The text buffer and other buffers too. You can leave the program without saving, do some work on the command line and go back to vi and continue the edit task.
The text buffer is restricted to 40 KiB. Large files have to be split up.
