\b0 informs the system whether you want to be notified when mail arrives during the current terminal session. The command biff y enables notification; the command biff n disables it. When mail notification is enabled, the header and first few lines of the message will be printed on your screen whenever mail arrives. A ``biff y'' command is often included in the file .login or .profile to be executed at each login. Biff operates asynchronously. For synchronous notification use the MAIL variable of sh(1) or the mail variable of csh(1).

\b0 is the server process which receives reports of incoming mail and notifies users if they have requested this service. Comsat receives messages on a datagram port associated with the ``biff'' service specification (see services(5) and inetd(8)). The one line messages are of the form user@mailbox-offset If the user specified is logged in to the system and the associated terminal has the owner execute bit turned on (by a ``biff y''), the offset is used as a seek offset into the appropriate mailbox file and the first 7 lines or 560 characters of the message are printed on the user's terminal. Lines which appear to be part of the message header other than the ``From'', ``To'', ``Date'', or ``Subject'' lines are not included in the displayed message.

The method embodies a public-key cryptosystem using knapsacks. To receive messages, use enroll; it asks you for a password that you must subsequently quote in order to receive secret mail. To receive secret mail, use xget. It asks for your password, then gives you the messages. To send secret mail, use xsend in the same manner as the ordinary mail command. (However, it will accept only one target). A message announcing the receipt of secret mail is also sent by ordinary mail.
\b0 waits until the specified time, then reminds you that you have to leave. You are reminded 5 minutes and 1 minute before the actual time, at the time, and every minute thereafter. When you log off, leave exits just before it would have printed the next message. The time of day is in the form hhmm where hh is a time in hours (on a 12 or 24 hour clock). All times are converted to a 12 hour clock, and assumed to be in the next 12 hours.

\b0 with argument n forbids messages via write and talk(1) by revoking non-user write permission on the user's terminal. Mesg with argument y reinstates permission. All by itself, mesg reports the current state without changing it.
\b0 retrieves mapping information for the ASCII keyboard to IBM 3270 terminal special functions. Normally, these mappings are found in /etc/map3270 (see map3270(5)). This information is used by the tn3270 command (see tn3270(1)).\
\b mset
\b0 can be used store the mapping information in the process environment in order to avoid scanning /etc/map3270 each time tn3270 is invoked. To do this, place the following command in your .login file:\
\b set noglob; setenv MAP3270 "`mset`"; unset noglob\
\b0 \
Mset first determines the user's terminal type from the environment variable TERM. Normally mset then uses the file /etc/map3270 to find the keyboard mapping for that terminal. However, if the environment variable MAP3270 exists and contains the entry for the specified terminal, then that definition is used. If the value of MAP3270 begins with a slash (`/') then it is assumed to be the full pathname of an alternate mapping file and that file is searched first. In any case, if the mapping for the terminal is not found in the environment, nor in an alternate map file, nor in the standard map file, then the same search is performed for an entry for a terminal type of unknown. If that search also fails, then a default mapping is used.
\b0 is used to read system messages. These messages are sent by mailing to the login `msgs' and should be short pieces of information which are suitable to be read once by most users of the system. Msgs is normally invoked each time you login, by placing it in the file .login (.profile if you use /bin/sh). It will then prompt you with the source and subject of each new message. If there is no subject line, the first few non-blank lines of the message will be displayed. If there is more to the message, you will be told how long it is and asked whether you wish to see the rest of the message.
\b0 not to say ``No new messages.''. This is useful in your .login file since this is often the case here

\b0 sends a message to one or more recipients, routing the message over whatever networks are necessary. Sendmail does internetwork forwarding as necessary to deliver the message to the correct place. Sendmail is not intended as a user interface routine; other programs provide user-friendly front ends; sendmail is used only to deliver pre-formatted messages. With no flags, sendmail reads its standard input up to an end-of-file or a line consisting only of a single dot and sends a copy of the message found there to all of the addresses listed. It determines the network(s) to use based on the syntax and contents of the addresses. Local addresses are looked up in a file and aliased appropriately. Aliasing can be prevented by preceding the address with a backslash. Normally the sender is not included in any alias expansions, e.g., if `john' sends to `group', and `group' includes `john' in the expansion, then the letter will not be delivered to `john'.

\b0 is a visual communication program which copies lines from your terminal to that of another user. If you wish to talk to someone on you own machine, then person is just the person's login name. If you wish to talk to a user on another host, then person is of the form : host!user or host.user or host:user or user@host though host@user is perhaps preferred. If you want to talk to a user who is logged in more than once, the ttyname argument may be used to indicate the appropriate terminal name. When first called, it sends the message Message from TalkDaemon@his_machine... talk: connection requested by your_name@your_machine. talk: respond with: talk your_name@your_machine to the user you wish to talk to. At this point, the recipient of the message should reply by typing talk your_name@your_machine It doesn't matter from which machine the recipient replies, as long as his login-name is the same. Once communication is established, the two parties may type simultaneously, with their output appearing in separate windows. Typing control L will cause the screen to be reprinted, while your erase, kill, and word kill characters will work in talk as normal. To exit, just type your interrupt character; talk then moves the cursor to the bottom of the screen and restores the terminal. Permission to talk may be denied or granted by use of the mesg command. At the outset talking is allowed. Certain commands, in particular nroff and pr(1) disallow messages in order to prevent messy output.

\b0 is the server that notifies a user that somebody else wants to initiate a conversation. It acts a repository of invitations, responding to requests by clients wishing to rendezvous to hold a conversation. In normal operation, a client, the caller, initiates a rendezvous by sending a CTL_MSG to the server of type LOOK_UP (see <protocols/talkd.h>). This causes the server to search its invitation tables to check if an invitation currently exists for the caller (to speak to the callee specified in the message). If the lookup fails, the caller then sends an ANNOUNCE message causing the server to broadcast an announcement on the callee's login ports requesting contact. When the callee responds, the local server uses the recorded invitation to respond with the appropriate rendezvous address and the caller and callee client programs establish a stream connection through which the conversation takes place.
\b0 permits a full-screen, full-duplex connection from a UNIX machine to an IBM machine running VM/CMS giving the appearance of being logged in directly to the remote machine on an IBM 3270 terminal. Of course you must have an account on the machine to which you wish to connect in order to log in. Tn3270 looks to the user in many respects like the Yale ASCII Terminal Communication System II. Tn3270 is actually a modification of the Arpanet TELNET user interface (see telnet(1)) that interprets and generates raw 3270 control streams. Emulation of the 3270 terminal is done in the Unix process. This emulation involves mapping 3270-style commands from the host into appropriate sequences to control the user's terminal screen. Tn3270 uses curses(3x) and the /etc/termcap file to do this. The emulation also involves simulating the special 3270 keyboard keys (program function keys, etc.) by mapping sequences of keystrokes from the ASCII keyboard into appropriate 3270 control strings. This mapping is terminal dependent and is specified in a description file, /etc/map3270, (see map3270(5)) or in an environment variable MAP3270 (see mset(1)). Any special function keys on the ASCII keyboard are used whenever possible. If an entry for the user's terminal is not found, tn3270 looks for an entry for the terminal type unknown. If this is not found, tn3270 uses a default keyboard mapping (see map3270(5)). The first character of each special keyboard mapping sequence is either an ASCII escape (ESC), a control character, or an ASCII delete (DEL). If the user types an unrecognized function key sequence, tn3270 sends an ASCII bell (BEL), or a visual bell if defined in the user's termcap entry, to the user's terminal and nothing is sent to the IBM host. If tn3270 is invoked without specifying a remote host system name, it enters local command mode, indicated by the prompt ``tn3270>''. In this mode, tn3270 accepts and executes the following commands: open connect to a remote host close close the current connection quit exit tn3270 z suspend tn3270 status print connection status ? print help information Other common telnet commands are not available in tn3270. Tn3270 command mode may also be entered, after connecting to a host, by typing a special escape character (typically control-C). While in command mode, any host login session is still alive but temporarily suspended. The host login session may be resumed by entering an empty line (press the RETURN key) in response to the command prompt. A session may be terminated by logging off the foreign host, or by typing ``quit'' or ``close'' while in local command mode.

\b0 returns a message to the sender of a message telling that you are on vacation. The intended use is in a .forward file. For example, your .forward file might have: , "|vacation eric" which would send messages to you (assuming your login name was eric) and send a message back to the sender. Vacation expects a file .vacation.msg in your home directory containing a message to be sent back to each sender. It should be an entire message (including headers). For example, it might say: From: eric@ucbmonet.Berkeley.EDU (Eric Allman) Subject: I am on vacation Delivered-By-The-Graces-Of: the Vacation program I am on vacation until July 22. If you have something urgent, please contact Joe Kalash <kalash@ucbingres.Berkeley.EDU>. --eric

\b0 reads its standard input until an end-of-file. It then sends this message, preceded by `Broadcast Message ...', to all logged in users. The sender should be super-user to override any protections the users may have invoked.
\b0 copies lines from your terminal to that of another user. When first called, it sends the message Message from yourname@yoursystem on yourttyname at time... The recipient of the message should write back at this point. Communication continues until an end of file is read from the terminal or an interrupt is sent. At that point write writes `EOT' on the other terminal and exits. If you want to write to a user who is logged in more than once, the ttyname argument may be used to indicate the appropriate terminal name. Permission to write may be denied or granted by use of the mesg command. At the outset writing is allowed. Certain commands, in particular nroff and pr(1) disallow messages in order to prevent messy output. If the character `!' is found at the beginning of a line, write calls the shell to execute the rest of the line as a command. The following protocol is suggested for using write: when you first write to another user, wait for him to write back before starting to send. Each party should end each message with a distinctive signal-(o) for `over' is conventionalthat the other may reply. (oo) for `over and out' is suggested when conversation is about to be terminated.
