Direct user input from keyboard is not possible. Complex interaction with the human user (data representation, and user input) has to be done by a non real-time Linux application communicated with the RTLinux application via shared memory or RT-FIFO's. These communication mechanisms are non-portable specific RTLinux facilities. Also, the access to the video and keyboard can not be done in real-time since it is delayed until Linux became active. RT-Terminal is a new component that allows to RTLinux applications display data directly on the console screen and read the pressed keys directly from the keyboard. RT-Terminal will provide direct access to the console to RTLinux applications and at the same time it will keep compatibility with the existing Linux console drivers. RT-Terminal will also be used by the Stand-Alone RTLinux component, since standalone can not use the linux kernel to print on the screen.
