POSIX does not specify this at all: https://pubs.opengroup.org/onlinepubs/9699919799/functions/ioctl.html I think this should be reverted as it breaks user-space code that dates back to 2003. ENOTTY doesn't even make sense anyway as it literally means "is not a terminal" and pseudo-ttys certainly are terminals.
