In addition to user programming access, it is desirable to have a
subsystem program at each HOST which makes the network immediately
accessible from the teletype without special programming. Subsystems
are commonly used system components such as text editors, compilers
and interpreters. The first network-related subsystem should allow
users at HOST A to connect to HOST B and appear as a regular terminal
user to HOST B. It is expected that more sophisticated subsystems
will be developed in time, but this basic one will render the early
net immediately useful.
