I think that Greg is slightly mistaken; `stty` had `-f` documented in Net/2
(1991, though of course the entanglements there have been discussed), but
the option existed in Reno (1990, though it seems to be absent from the man
page).

I'm curious who was using AOS, which was essentially Tahoe+NFS.
"Frog-marched" is an apt description of the forced migration from SunOS to
Solaris.
