stty: tcgetattr: A specified file does not support the ioctl system call.

Answer : tcgetattr

If you know the ksh file that the cron job is running, then remove the refrences for stty command from that file. A cron job which is non interactive doesn't require any terminal (tty) related commands. It would have been placed there for some testing and all but you can remove them if there's no impact.
