No, you need to give up and build "force" only on machines whose operating
system supports the operation needed for a process to be able to force
characters to be "typed" on another terminal.  TIOCSTI is an "ioctl" that
takes a character and makes the terminal referred to by the file descriptor
argument act as if that character had been typed on it.  If you don't have
this "ioctl", or something like it, you can't make "force" work.
