- THIS IS A LARGE FILE AND IS ADVISED YOU BUFFER THE INFORMATION
-
- The Telnet menu system allows you to easily pick sites to Telnet to. The
- menu system allows you to move from one directory to another and page from
- one to the next. It even allows you to pick from sites listed in your
- personal notebook database file (see document file labeled "NOTE").
- c6
- Commands listed on the Telnet menu are:
-
- c5# c1Number of the menu item
- ccThis option allows you to pick from the available listing
- show to you on your screen. The listing can either be a
- subdirectory (ie MENU) or a site description. Entering the
- number of the site list will send you directly to the Telnet
- client and attempt a connection to the site.
-
- c5P c1Move to previous page
- ccThis option only appears if there is a previous page of
- available to display.
-
- c5N c1Move to next page
- ccThis option only appears if there is another page ahead of
- the current page on the display.
-
- c5M c1Call up notebook entries
- ccThis option only appears if there are notebook entries in
- your notebook database file for Telnet (See help file on NOTEBOOK).
- Choosing this option (if available) will pull up your entries
- from your Telnet database and allow you to choose from the selected
- list.
-
- c5Q c1Quit and return to INetShell main menu
- ccThis option will return you to the INetShell main menu.

- NAME
- telnet - user interface to a remote system using the TELNET
- protocol
-
- DESCRIPTION
- telnet communicates with another host using the TELNET pro-
- tocol. If telnet is invoked without arguments, it enters
- command mode, indicated by its prompt (telnet>). In this
- mode, it accepts and executes the commands listed below. If
- it is invoked with arguments, it performs an open command
- (see below) with those arguments.
-
- Once a connection has been opened, telnet enters input mode.
- In this mode, text typed is sent to the remote host. The
- input mode entered will be either "character at a time" or
- "line by line" depending on what the remote system supports.
-
- In "character at a time" mode, most text typed is immedi-
- ately sent to the remote host for processing.
-
- In "line by line" mode, all text is echoed locally, and
- (normally) only completed lines are sent to the remote host.
- The "local echo character" (initially `^E') may be used to
- turn off and on the local echo (this would mostly be used to
- enter passwords without the password being echoed).
-
- In either mode, if the localchars toggle is TRUE (the
- default in line mode; see below), the user's quit, intr, and
- flush characters are trapped locally, and sent as TELNET
- protocol sequences to the remote side. There are options
- (see toggle autoflush and toggle autosynch below) which
- cause this action to flush subsequent output to the terminal
- (until the remote host acknowledges the TELNET sequence) and
- flush previous terminal input (in the case of quit and
- intr).
-
- While connected to a remote host, telnet command mode may be
- entered by typing the telnet "escape character" (initially
- `^]', (control-right-bracket)). When in command mode, the
- normal terminal editing conventions are available.
-
- USAGE
- Telnet Commands
-
- The following commands are available. Only enough of each
- command to uniquely identify it need be typed (this is also
- true for arguments to the mode, set, toggle, and display
- commands).
-
- open host [ port ]
- Open a connection to the named host. If no port number
- is specified, telnet will attempt to contact a TELNET
- server at the default port. The host specification may
- be either a host name or an Internet address specified
- in the "dot notation".
-
- close
- Close a TELNET session and return to command mode.
-
- quit Close any open TELNET session and exit telnet. An EOF
- (in command mode) will also close a session and exit.
-
- mode type
- type is either line (for "line by line" mode) or char-
- acter (for "character at a time" mode). The remote
- host is asked for permission to go into the requested
- mode. If the remote host is capable of entering that
- mode, the requested mode will be entered.
-
- status
- Show the current status of telnet. This includes the
- peer one is connected to, as well as the current mode.
-
- display [ argument... ]
- Display all, or some, of the set and toggle values (see
- below).
-
- ? [ command ]
- Get help. With no arguments, telnet prints a help sum-
- mary. If a command is specified, telnet will print the
- help information for just that command.
-
- ^d
- Send control-d to the host.
-
- send arguments
- Send one or more special character sequences to the
- remote host. The following are the arguments which may
- be specified (more than one argument may be specified
- at a time):
-
- escape
- Send the current telnet escape character (ini-
- tially `^]').
-
- synch
- Send the TELNET SYNCH sequence. This sequence
- causes the remote system to discard all previously
- typed (but not yet read) input. This sequence is
- sent as TCP urgent data (and may not work if the
- remote system is a 4.2 BSD system -- if it does
- not work, a lower case "r" may be echoed on the
- terminal).
-
- brk Send the TELNET BRK (Break) sequence, which may
- have significance to the remote system.
-
- ip Send the TELNET IP (Interrupt Process) sequence,
- which should cause the remote system to abort the
- currently running process.
-
- ao Sends the TELNET AO (Abort Output) sequence, which
- should cause the remote system to flush all output
- from the remote system to the user's terminal.
-
- ayt Sends the TELNET AYT (Are You There) sequence, to
- which the remote system may or may not choose to
- respond.
-
- ec Sends the TELNET EC (Erase Character) sequence,
- which should cause the remote system to erase the
- last character entered.
-
- el Sends the TELNET EL (Erase Line) sequence, which
- should cause the remote system to erase the line
- currently being entered.
-
- ga Sends the TELNET GA (Go Ahead) sequence, which
- likely has no significance to the remote system.
-
- nop Sends the TELNET NOP (No Operation) sequence.
-
- ? Prints out help information for the send command.
-
- set argument value
- Set any one of a number of telnet variables to a
- specific value. The special value "off" turns off the
- function associated with the variable. The values of
- variables may be interrogated with the display command.
- The variables which may be specified are:
-
- echo This is the value (initially `^E') which, when in
- "line by line" mode, toggles between doing local
- echoing of entered characters (for normal process-
- ing), and suppressing echoing of entered charac-
- ters (for entering, say, a password).
-
- escape
- This is the telnet escape character (initially
- `^[') which causes entry into telnet command mode
- (when connected to a remote system).
-
- interrupt
- If telnet is in localchars mode (see toggle local-
- chars below) and the interrupt character is typed,
- a TELNET IP sequence (see send ip above) is sent
- to the remote host. The initial value for the
- interrupt character is taken to be the terminal's
- intr character.
-
- quit If telnet is in localchars mode (see toggle local-
- chars below) and the quit character is typed, a
- TELNET BRK sequence (see send brk above) is sent
- to the remote host. The initial value for the
- quit character is taken to be the terminal's quit
- character.
-
- flushoutput
- If telnet is in localchars mode (see toggle local-
- chars below) and the flushoutput character is
- typed, a TELNET AO sequence (see send ao above) is
- sent to the remote host. The initial value for
- the flush character is taken to be the terminal's
- flush character.
-
- erase
- If telnet is in localchars mode (see toggle local-
- chars below), and if telnet is operating in "char-
- acter at a time" mode, then when this character is
- typed, a TELNET EC sequence (see send ec above) is
- sent to the remote system. The initial value for
- the erase character is taken to be the terminal's
- erase character.
-
- kill If telnet is in localchars mode (see toggle local-
- chars below), and if telnet is operating in "char-
- acter at a time" mode, then when this character is
- typed, a TELNET EL sequence (see send el above) is
- sent to the remote system. The initial value for
- the kill character is taken to be the terminal's
- kill character.
-
- eof If telnet is operating in "line by line" mode,
- entering this character as the first character on
- a line will cause this character to be sent to the
- remote system. The initial value of the eof char-
- acter is taken to be the terminal's eof character.
-
- toggle arguments...
- Toggle (between TRUE and FALSE) various flags that con-
- trol how telnet responds to events. More than one
- argument may be specified. The state of these flags
- may be interrogated with the display command. Valid
- arguments are:
-
- localchars
- If this is TRUE, then the flush, interrupt, quit,
- erase, and kill characters (see set above) are
- recognized locally, and transformed into (hope-
- fully) appropriate TELNET control sequences
- (respectively ao, ip, brk, ec, and el; see send
- above). The initial value for this toggle is TRUE
- in "line by line" mode, and FALSE in "character at
- a time" mode.
-
- autoflush
- If autoflush and localchars are both TRUE, then
- when the ao, intr, or quit characters are recog-
- nized (and transformed into TELNET sequences; see
- set above for details), telnet refuses to display
- any data on the user's terminal until the remote
- system acknowledges (via a TELNET Timing Mark
- option) that it has processed those TELNET
- sequences. The initial value for this toggle is
- TRUE if the terminal user had not done an "stty
- noflsh", otherwise FALSE (see stty(1V)).
-
- autosynch
- If autosynch and localchars are both TRUE, then
- when either the intr or quit characters is typed
- (see set above for descriptions of the intr and
- quit characters), the resulting TELNET sequence
- sent is followed by the TELNET SYNCH sequence.
- This procedure should cause the remote system to
- begin throwing away all previously typed input
- until both of the TELNET sequences have been read
- and acted upon. The initial value of this toggle
- is FALSE.
-
- crmod
- Toggle RETURN mode. When this mode is enabled,
- most RETURN characters received from the remote
- host will be mapped into a RETURN followed by a
- LINEFEED. This mode does not affect those charac-
- ters typed by the user, only those received from
- the remote host. This mode is not very useful
- unless the remote host only sends RETURN, but
- never LINEFEED. The initial value for this toggle
- is FALSE.
-
- debug
- Toggle socket level debugging (useful only to the
- super-user). The initial value for this toggle is
- FALSE.
-
- options
- Toggle the display of some internal telnet proto-
- col processing (having to do with TELNET options).
- The initial value for this toggle is FALSE.
-
- netdata
- Toggle the display of all network data (in hexade-
- cimal format). The initial value for this toggle
- is FALSE.
-
- ? Display the legal toggle commands.
-
- BUGS
- There is no adequate way for dealing with flow control.
-
- On some remote systems, echo has to be turned off manually
- when in "line by line" mode.
-
- There is enough settable state to justify a .telnetrc file.
-
- No capability for a .telnetrc file is provided.
-
- In "line by line" mode, the terminal's EOF character is only
- recognized (and sent to the remote system) when it is the
- first character on a line.
