RE: streams based tcpip vs character based tcpip

        The difference is that streams based tcpip is built with stream drivers
        and modules where character based tcpip is built with UNIX V or BSD
        character device drivers. Two different technologies.

Actually, BSD doesn't use character device drivers in the traditional
sense. They use a different approach, with a network interface which
provides a dispatch table (somewhat like the character or block
device interface).

As I remember, the networking code for Version 6 UNIX did the standard
device model, but I forget the details. (Their might be an RFC on it.)
