What you had was the right idea, except it should use unsigned char
instead of char, to be portable to (admittedly weird) systems where
char is signed and there's integer overflow checking so an exception
is raised when storing (say) 255 into a char variable.  So this is a
bit better:

  int c;
  while ((c = getchar ()) != EOF)
    {
      unsigned char u = c;
      write (file_descriptor, &u, 1);
    }
