termio TCSETAF bug

> First, is this a bug in the documentation or in the tty code?

I would consider it a bug in the tty code; the author probably thought it was
OK to include output, since it had obviously made it all out to the terminal,
and didn't consider something such as pseudo-ttys or "rlogin" (which didn't
exist in S5R3).

The man page.  None of the original S5 code was used in the 4.0 driver, since
the 4.0 tty subsystem is streams-based....
