It's not clear just what point you're trying to make.

ENOTTY has a special meaning as a return value from an ioctl call in
some contexts (it specifically means the called routine did not handle
the command and other routines hooked into the ioctl call chain may be
able to do the job).

In addition, the strerror() output for ENOTTY says nothing about a
typewriter, the text is "Inappropriate ioctl for device."
