asetniop-term

An asetniop keyboard emulator for linux terminals.

Build Instructions

asetniop-term is built with make. It accepts the device node of the keyboard as its first argument, e.g.:

> make
# ./asetniop.exe /dev/input/by-path/*-kbd

Either run asetniop-term as root, or make sure your user has read permissions on the device node (the absolute device node, not the symlink).

Debugging

To debug, set the DEBUG env var to:

• DEBUG to show device acquisition
• DEBUG_EVENT to show keydown and keyup events
• DEBUG_STATE to show the asetniop state

like so:

> DEBUG=DEBUG_STATE make

Disabling input

asetniop-term disables the terminal echo and ignores stdin. After running, the terminal should be back to its normal state, but if not, stty echo should fix it.

asetniop-term does not prevent key events being read by other processes, like X11. To disable the keyboard under X11 (make sure you have some other way to control the system!) - find the device id like so:

> xinput
⎡ Virtual core pointer                      id=2    [master pointer  (3)]
⎜ ↳ ...
⎣ Virtual core keyboard                     id=3    [master keyboard (2)]
    ↳ ...
    ↳ AT Translated Set 2 keyboard              id=10   [slave  keyboard (3)]

Then disable the device, e.g.:

> xinput disable 10

Todo

• Look at pushing output to other applications?
• Write a kernel module to emulate a real keyboard?
