Well, if you whip out your handy-dandy "System V, Release 3.2" Release Notes,
page 6-46 says,
	"   In the next major release of UNIX System V, the current character-based
TTY subsystem will be replaced with a STERAMS-based version the TTY subsystem...
The new TTY subsystem will include STREAMS-based versions of the 3b2 console
driver, PORTS, HIPORTS, and EPORTS drivers as well as a STREAMS-based module
called LDTERM.  LDTERM will support both the UNIX System V termio(7) line
discipline and the TERMIOS line discipline as specifed in the POSIX standard."

Now, we need a definition of "the next major release of UNIX System V", that would
probably be Release 4.
