Is there any way for software to be able to simulate being a second keyboard which is attached to a specifyable virtual tty? I would like to write some software which takes over, say, tty9, and becomes a virtual terminal. I know that /dev/vcs9 and/or /dev/vcsa9 can be used to gain knowledge of the screen content. The two things I do not know how to do are:
1) How can the software enqueue input so that those characters will be read from /dev/tty9?
2) How can the software know when the screen has been modified? This would preferrably be interrupt driven, and would indicate the area of the screen which has changed.
