Here we're gonna create a terminal emulator reusing the code ported from Gramado OS. Read TODO.TXT.
* This is the virtual terminal, terminal.bin. It is a client-side GUI application.
* It has an embedded command line interface receaving system message.
* At the second stage it is able to receive input from stderr, sent by the shell. Type 'start-shell'.
* The plan is to use the tty infrastructure.
