 3 Syntax:  logout {-control_args}
 4 
 5 
 6 Function: terminates your session and ends communication with the
 7 Multics system.  It is used from a terminal that is logged in but not
 8 connected to a process.  (See "Notes on disconnected processes" in
 9 login.info.) It informs the answering service that the user who gave a
10 correct Person_id-password combination is no longer using the
11 terminal.
12 
13 
14 Control arguments:
15 -brief, -bf
16    prints neither the logout message nor, if you give -hold, the login
17    message.
18 -hold, -hd
19    terminates your session but not communication with the system:  you
20    can immediately log in without redialing.
21 -long, -lg
22    prints both the logout message, and if -hold is given, the login
23    message. (Default)
24 -no_hold, -nhd
25    terminates your session and drops your communication line. (Default)

28 Notes: If your site is security conscious, it may have disabled
29 "logout -hold"; in this case if you wish to change authorization, do
30 this:
31    1. log out
32    2. verify, using terminal/modem indications, that the terminal has
33       dropped DTR and that the system acknowledged by dropping DSR
34    3. log in at the new authorization.
35 
36 This procedure is the only way to guarantee that you are communicating
37 with the answering service and not with a Trojan horse.
