T\bTi\bip\bp and _\bc_\bu establish a full-duplex connection to another machine, giving
the appearance of being logged in directly on the remote cpu. It goes
without saying that you must have a login on the machine (or equivalent)
to which you wish to connect. The preferred interface is t\bti\bip\bp. The _\bc_\bu
interface is included for those people attached to the ``call UNIX'' com-
mand of version 7. This manual page describes only t\bti\bip\bp.
Available Option:
-\b-v\bv Set verbose mode.
Typed characters are normally transmitted directly to the remote machine
(which does the echoing as well). A tilde (`~') appearing as the first
character of a line is an escape signal; the following are recognized:
~\b~^\b^D\bD ~\b~.
Drop the connection and exit (you may still be logged in on the re-
mote machine).
~\b~c\bc [_\bn_\ba_\bm_\be]
Change directory to _\bn_\ba_\bm_\be (no argument implies change to your home
directory).
~\b~!\b! Escape to a shell (exiting the shell will return you to tip).
~\b~>\b> Copy file from local to remote. T\bTi\bip\bp prompts for the name of a lo-
cal file to transmit.
~\b~<\b< Copy file from remote to local. T\bTi\bip\bp prompts first for the name of
the file to be sent, then for a command to be executed on the re-
mote machine.
~\b~p\bp _\bf_\br_\bo_\bm [_\bt_\bo]
Send a file to a remote UNIX host. The put command causes the
remote UNIX system to run the command string ``cat > 'to''', while
t\bti\bip\bp sends it the ``from'' file. If the ``to'' file isn't specified
the ``from'' file name is used. This command is actually a UNIX
specific version of the ``~>'' command.
~\b~t\bt _\bf_\br_\bo_\bm [_\bt_\bo]
Take a file from a remote UNIX host. As in the put command the
``to'' file defaults to the ``from'' file name if it isn't
specified. The remote host executes the command string ``cat
'from';echo ^A'' to send the file to t\bti\bip\bp.
~\b~ Pipe the output from a remote command to a local UNIX process. The
command string sent to the local UNIX system is processed by the
shell.
~\b~$\b$ Pipe the output from a local UNIX process to the remote host. The
command string sent to the local UNIX system is processed by the
shell.
~\b~#\b# Send a BREAK to the remote system. For systems which don't support
the necessary _\bi_\bo_\bc_\bt_\bl call the break is simulated by a sequence of
line speed changes and DEL characters.
~\b~s\bs Set a variable (see the discussion below).
~\b~^\b^Z\bZ Stop t\bti\bip\bp (only available with job control).
~\b~^\b^Y\bY Stop only the ``local side'' of t\bti\bip\bp (only available with job con-
trol); the ``remote side'' of t\bti\bip\bp, the side that displays output
from the remote host, is left running.

T\bTi\bip\bp uses the file /_\be_\bt_\bc/_\br_\be_\bm_\bo_\bt_\be to find how to reach a particular system
and to find out how it should operate while talking to the system; refer
to remote(5) for a full description. Each system has a default baud rate
with which to establish a connection. If this value is not suitable, the
baud rate to be used may be specified on the command line, e.g. ``tip
-300 mds''.
When t\bti\bip\bp establishes a connection it sends out a connection message to
the remote system; the default value, if any, is defined in /_\be_\bt_\bc/_\br_\be_\bm_\bo_\bt_\be
(see remote(5)).
When t\bti\bip\bp prompts for an argument (e.g. during setup of a file transfer)
the line typed may be edited with the standard erase and kill characters.
A null line in response to a prompt, or an interrupt, will abort the di-
alogue and return you to the remote machine.
T\bTi\bip\bp guards against multiple users connecting to a remote system by open-
ing modems and terminal lines with exclusive access, and by honoring the
locking protocol used by uucp(1).
During file transfers t\bti\bip\bp provides a running count of the number of lines
transferred. When using the ~> and ~< commands, the ``eofread'' and
``eofwrite'' variables are used to recognize end-of-file when reading,
and specify end-of-file when writing (see below). File transfers normal-
ly depend on tandem mode for flow control. If the remote system does not
support tandem mode, ``echocheck'' may be set to indicate t\bti\bip\bp should syn-
chronize with the remote system on the echo of each transmitted charac-
ter.
When t\bti\bip\bp must dial a phone number to connect to a system it will print
various messages indicating its actions. T\bTi\bip\bp supports the DEC DN-11 and
Racal-Vadic 831 auto-call-units; the DEC DF02 and DF03, Ventel 212+,
Racal-Vadic 3451, and Bizcomp 1031 and 1032 integral call unit/modems.
V\bVA\bAR\bRI\bIA\bAB\bBL\bLE\bES\bS
T\bTi\bip\bp maintains a set of _\bv_\ba_\br_\bi_\ba_\bb_\bl_\be_\bs which control its operation. Some of
these variable are read-only to normal users (root is allowed to change
anything of interest). Variables may be displayed and set through the
``s'' escape. The syntax for variables is patterned after vi(1) and
Mail(1). Supplying ``all'' as an argument to the set command displays
all variables readable by the user. Alternatively, the user may request
display of a particular variable by attaching a `?' to the end. For ex-
ample ``escape?'' displays the current escape character.
Variables are numeric, string, character, or boolean values. Boolean
variables are set merely by specifying their name; they may be reset by
prepending a `!' to the name. Other variable types are set by con-
catenating an `=' and the value. The entire assignment must not have any
blanks in it. A single set command may be used to interrogate as well as
set a number of variables. Variables may be initialized at run time by
placing set commands (without the ``~s'' prefix in a file ._\bt_\bi_\bp_\br_\bc in one's
home directory). The -\b-v\bv option causes t\bti\bip\bp to display the sets as they
are made. Certain common variables have abbreviations. The following is
a list of common variables, their abbreviations, and their default
values.
_\bb_\be_\ba_\bu_\bt_\bi_\bf_\by (bool) Discard unprintable characters when a session is being
scripted; abbreviated _\bb_\be.
_\bb_\ba_\bu_\bd_\br_\ba_\bt_\be (num) The baud rate at which the connection was established;
abbreviated _\bb_\ba.
_\bd_\bi_\ba_\bl_\bt_\bi_\bm_\be_\bo_\bu_\bt
(num) When dialing a phone number, the time (in seconds) to
wait for a connection to be established; abbreviated _\bd_\bi_\ba_\bl.
_\be_\bc_\bh_\bo_\bc_\bh_\be_\bc_\bk (bool) Synchronize with the remote host during file transfer
by waiting for the echo of the last character transmitted;
default is _\bo_\bf_\bf.
_\be_\bo_\bf_\br_\be_\ba_\bd (str) The set of characters which signify and end-of-
tranmission during a ~< file transfer command; abbreviated
_\be_\bo_\bf_\br.
_\be_\bo_\bf_\bw_\br_\bi_\bt_\be (str) The string sent to indicate end-of-transmission during
a ~> file transfer command; abbreviated _\be_\bo_\bf_\bw.
_\be_\bo_\bl (str) The set of characters which indicate an end-of-line.
T\bTi\bip\bp will recognize escape characters only after an end-of-
line.
_\be_\bs_\bc_\ba_\bp_\be (char) The command prefix (escape) character; abbreviated _\be_\bs;
default value is `~'.
_\be_\bx_\bc_\be_\bp_\bt_\bi_\bo_\bn_\bs
(str) The set of characters which should not be discarded due
to the beautification switch; abbreviated _\be_\bx; default value
is ``\t\n\f\b''.
_\bf_\bo_\br_\bc_\be (char) The character used to force literal data transmission;
abbreviated _\bf_\bo; default value is `^P'.
_\bf_\br_\ba_\bm_\be_\bs_\bi_\bz_\be (num) The amount of data (in bytes) to buffer between file
system writes when receiving files; abbreviated _\bf_\br.
_\bh_\bo_\bs_\bt (str) The name of the host to which you are connected; abbre-
viated _\bh_\bo.
_\bp_\br_\bo_\bm_\bp_\bt (char) The character which indicates and end-of-line on the
remote host; abbreviated _\bp_\br; default value is `\n'. This
value is used to synchronize during data transfers. The
count of lines transferred during a file transfer command is
based on recipt of this character.
_\br_\ba_\bi_\bs_\be (bool) Upper case mapping mode; abbreviated _\br_\ba; default value
is _\bo_\bf_\bf. When this mode is enabled, all lower case letters
will be mapped to upper case by t\bti\bip\bp for transmission to the
remote machine.
_\br_\ba_\bi_\bs_\be_\bc_\bh_\ba_\br (char) The input character used to toggle upper case mapping
mode; abbreviated _\br_\bc; default value is `^A'.
_\br_\be_\bc_\bo_\br_\bd (str) The name of the file in which a session script is
recorded; abbreviated _\br_\be_\bc; default value is ``tip.record''.
_\bs_\bc_\br_\bi_\bp_\bt (bool) Session scripting mode; abbreviated _\bs_\bc; default is
_\bo_\bf_\bf. When _\bs_\bc_\br_\bi_\bp_\bt is true, t\bti\bip\bp will record everything
transmitted by the remote machine in the script record file
specified in _\br_\be_\bc_\bo_\br_\bd. If the _\bb_\be_\ba_\bu_\bt_\bi_\bf_\by switch is on, only
printable ASCII characters will be included in the script
file (those characters betwee 040 and 0177). The variable
_\be_\bx_\bc_\be_\bp_\bt_\bi_\bo_\bn_\bs is used to indicate characters which are an excep-
tion to the normal beautification rules.
_\bt_\ba_\bb_\be_\bx_\bp_\ba_\bn_\bd (bool) Expand tabs to spaces during file transfers; abbrevi-
ated _\bt_\ba_\bb; default value is _\bf_\ba_\bl_\bs_\be. Each tab is expanded to 8
spaces.
_\bv_\be_\br_\bb_\bo_\bs_\be (bool) Verbose mode; abbreviated _\bv_\be_\br_\bb; default is _\bt_\br_\bu_\be. When
verbose mode is enabled, t\bti\bip\bp prints messages while dialing,
shows the current number of lines transferred during a file
transfer operations, and more.
