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.

Simple Dialogue -- PDP-10 to 940
A user at Utah is sitting at a teletype dialed into the University's
dual PDP-10's. He wishes to operate the CAL sub-system on the 940 at
SRI in Menlo Park, California.

------------ is issued to call and start
the TELNET subsystem.
*ESCAPE CHARACTER IS # The user indicates an escape
------------------------- character which TELNET
will watch for in subsequent
input from the user.
*CONNECT TO SRI The TELNET subsystem will make
------------------ the appropriate system call
(UUO) to establish a primary
connection. The connection
will be established, provided:
1. SRI is willing to accept
another foreign user;
2. The UTAH user is cleared
for network access at UTAH.
This is determined by a
status word kept in the PDP-10
monitor for each user.
