BSD 4.4 Lite was released in 1994.  (Lite2 was released in 1995.)

Linux was started in 1991, and we had a stty from very early on --- by
1992 at the latest.

Most of the Linux kernel developers from those early days cut their
teeth on BSD 4.3 and BSD 4.3 Reno, and were unwillingly frog-marched
from Sun OS 4.x to Slowlaris 2.x, and from IBM AOS (which was also BSD
4.3 based) to IBM AIX (thanks, AT&T) in their day jobs.
