GUI programs such as Notepad usually don't read from STDIN, which is
where text goes if you write to a pipe. You may have to check out how,
exactly, the program accepts commands; your autoIT script is probably
sending keystrokes using the Wndows GUI, so it works as long as the
program has focus.

Ideally, look into whether the program has an actual automation mode -
and if it doesn't have one, ask the programmer to expose his code
directly to a Python script. Hey, it's worth a shot! :)
