"the 8th edition system including Streams was already pretty
much in place by the time that Robert Morris adapted
the then-current BSD TCP/IP stack to streams. At that time,
we were using either serial communication over various modems,
and more notably Datakit. Looking back at this, one of
the satisfying things is that the communication structure
built then was adaptable so smoothly to TCP/IP when
the protocol's importance became undeniable."
