It was a learning experience for me... you've missed out a few dead ends
and another peice of code that works differently but only once per login :(
I can't figure out what's wrong with it... (I guess I'm assuming something
in the init/deinit code but can't figure out what)

it's basically the unix analogue of dos.h

termio functions and constants  IIRC  (I just copies tyhem from man-pages

not my idea there... I'm still scared of threads
can you post example code?

The bit that uses termios turns off that feature.
but don't use stdin (FILE* type stream) based functions as they're
buffered, use read() directly on STDIN_FILENO  (or 0 if you're feeling
lazy)
