   16-bit Windows doesn't have standard output/input handles. It only has   
   pipes. DOS devices such as `con` and `aux` are named pipes. They're not   
   recognized as standard output/input. 16-bit Windows doesn't have any   
   `GetStdHandle()` function or constants such as `STD_OUTPUT_HANDLE`.

   16-bit Windows NE module does not support a Console flag for the program   
   type. 16-bit Windows programs can not have their own console(s), by design.   
   Only DOS programs do. Period.

   Yes, but that console would have to be provided by a separate DOS program.   
   If you're developing you own OS, then you can do whatever you want.
