A year would be about right to incorporate some of the new stuff. Well, maybe I was mistaken and 1987 was the year of NeWS and 1988 was the year of SunOS-4.0. > But getting back to your original comment that you are not aware of any streams implementation before SunOS-4.0, do you mean that it was the first you became aware of? Certainly System V, from whence it came, predated SunOS-4.0 and 8th Edition predated that. My copy of the tty_ld(4) man page was printed Feb 10, 1985. SVr4 was the first "SystemV" with a streams based tty driver and this driver was the driver taken from SunOS-4.0. You can verify this by looking at the bug-fix that was needed to make it work at all. The AT&T concept had a bug as it did not allow to switch from raw mode to cooked mode mode without loosing all characters in the buffer. Sun fixed this by introducing a new mesage that says: Someone is going to read 5 chars, so transfer 5 chars from the edit-buffer upstream but keep the rest.
