NAME
tip - connect to remote system
SYNOPSIS
tip [-v] [-speed-entry] {hostname | phone-number | device}
DESCRIPTION
The tip utility establishes a full-duplex terminal connection to a
remote host. Once the connection is established, a remote session using
tip behaves like an interactive session on a local terminal.
The remote file contains entries describing remote systems and line
speeds used by tip.
Each host has a default baud rate for the connection, or you can spec‐
ify a speed with the -speed-entry command line argument.
When phone-number is specified, tip looks for an entry in the remote
file of the form:
tip -speed-entry
When tip finds such an entry, it sets the connection speed accordingly.
If it finds no such entry, tip interprets -speed-entry as if it were a
system name, resulting in an error message.
If you omit -speed-entry, tip uses the tip0 entry to set a speed for
the connection.
When device is specified, tip attempts to open that device, but will do
so using the access privileges of the user, rather than tip's usual
access privileges (setgid dialout). The user must have read/write
access to the device. The tip utility interprets any character string
beginning with the slash character (/) as a device name.
When establishing the connection, tip sends a connection message to the
remote system. The default value for this message can be found in the
remote file.
When tip attempts to connect to a remote system, it opens the associ‐
ated device with an exclusive-open ioctl(2) call. Thus, only one user
at a time may access a device. This is to prevent multiple processes
from sampling the terminal line.
When tip starts up, it reads commands from the file .tiprc in your home
directory.
OPTIONS
-v Display commands from the .tiprc file as they are executed.
USAGE
Typed characters are normally transmitted directly to the remote
machine, which does the echoing as well.
At any time that tip prompts for an argument (for example, 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, aborts the dialogue and returns you to the remote machine.
Commands
A tilde (~) appearing as the first character of a line is an escape
signal which directs tip to perform some special action. tip recognizes
the following escape sequences:
~^D Drop the connection and exit (you may still be logged
~. in on the remote machine). Note: If you rlogin and
then run tip on the remote host, you must type ~~.
(tilde tilde dot) to end the tip session. If you type
~. (tilde dot), it terminates the rlogin.
~c [name] Change directory to name. No argument implies change
to your home directory.
~! Escape to an interactive shell on the local machine.
Exiting the shell returns you to tip.
~> Copy file from local to remote.
~< Copy file from remote to local.
~p from [ to ] Send a file to a remote host running the UNIX system.
When you use the put command, the remote system runs
the command string
cat > to
while tip sends it the from file. If the to file is
not specified, the from file name is used. This com‐
mand is actually a UNIX-system-specific version of
the '~>' command.
~t from [ to ] Take a file from a remote host running the UNIX sys‐
tem. As in the put command the to file defaults to
the from file name if it is not specified. The remote
host executes the command string
cat from; echo ^A
to send the file to tip.
~| Pipe the output from a remote command to a local
process. The command string sent to the local system
is processed by the shell.
~C Connect a program to the remote machine. The command
string sent to the program is processed by the shell.
The program inherits file descriptors 0 as remote
line input, 1 as remote line output, and 2 as tty
standard error.
~$ Pipe the output from a local process to the remote
host. The command string sent to the local system is
processed by the shell.
~# Send a BREAK to the remote system.
~s Set a variable (see the discussion below).
~^Z Stop tip. Only available when run under a shell that
supports job control, such as the C shell.
~^Y Stop only the "local side" of tip. Only available
when run under a shell that supports job control,
such as the C shell. The "remote side" of tip, that
is, the side that displays output from the remote
host, is left running.
~? Get a summary of the tilde escapes.
Copying files requires some cooperation on the part of the remote host.
When a ~> or ~< escape is used to send a file, tip prompts for a file
name (to be transmitted or received) and a command to be sent to the
remote system, in case the file is being transferred from the remote
system. While tip is transferring a file, the number of lines trans‐
ferred will be continuously displayed on the screen. A file transfer
may be aborted with an interrupt.
Auto-call Units
tip may be used to dial up remote systems using a number of auto-call
unit's (ACUs). When the remote system description contains the du capa‐
bility, tip uses the call-unit (cu), ACU type (at), and phone numbers
(pn) supplied. Normally, tip displays verbose messages as it dials.
Depending on the type of auto-dialer being used to establish a connec‐
tion, the remote host may have garbage characters sent to it upon con‐
nection. The user should never assume that the first characters typed
to the foreign host are the first ones presented to it. The recommended
practice is to immediately type a kill character upon establishing a
connection (most UNIX systems either support @ or Control-U as the ini‐
tial kill character).
tip currently supports the Ventel MD-212+ modem and DC Hayes-compatible
modems.
When tip initializes a Hayes-compatible modem for dialing, it sets up
the modem to auto-answer. Normally, after the conversation is complete,
tip drops DTR, which causes the modem to "hang up."
Most modems can be configured so that when DTR drops, they re-initial‐
ize themselves to a preprogrammed state. This can be used to reset the
modem and disable auto-answer, if desired.
Additionally, it is possible to start the phone number with a Hayes S
command so that you can configure the modem before dialing. For exam‐
ple, to disable auto-answer, set up all the phone numbers in
/etc/remote using something like pn=S0=0DT5551212. The S0=0 disables
auto-answer.
Remote Host Description
Descriptions of remote hosts are normally located in the system-wide
file /etc/remote. However, a user may maintain personal description
files (and phone numbers) by defining and exporting the REMOTE shell
variable. The remote file must be readable by tip, but a secondary file
describing phone numbers may be maintained readable only by the user.
This secondary phone number file is /etc/phones, unless the shell vari‐
able PHONES is defined and exported. The phone number file contains
lines of the form:
system-name phone-number
Each phone number found for a system is tried until either a connection
is established, or an end of file is reached. Phone numbers are con‐
structed from '0123456789−=*', where the '=' and '*' are used to indi‐
cate a second dial tone should be waited for (ACU dependent).
tip Internal Variables
tip maintains a set of variables which are used in normal operation.
Some of these variables 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 ~s escape dis‐
plays all variables that the user can read. Alternatively, the user may
request display of a particular variable by attaching a ? to the end.
For example, '~s escape?' displays the current escape character.
Variables are numeric (num), string (str), character (char), or Boolean
(bool) 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 appending 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 runtime by placing set commands (with‐
out the ~s prefix) in a .tiprc file in one's home directory. The -v
option makes tip display the sets as they are made. Comments preceded
by a # sign can appear in the .tiprc file.
Finally, the variable names must either be completely specified or an
abbreviation may be given. The following list details those variables
known to tip.
beautify (bool) Discard unprintable characters when a session is
being scripted; abbreviated be. If the nb capability is
present, beautify is initially set to off. Otherwise,
beautify is initially set to on.
baudrate (num) The baud rate at which the connection was estab‐
lished; abbreviated ba. If a baud rate was specified on
the command line, baudrate is initially set to the
specified value. Or, if the br capability is present,
baudrate is initially set to the value of that capabil‐
ity. Otherwise, baudrate is set to 300 baud. Once tip
has been started, baudrate can only changed by the
super-user.
dialtimeout (num) When dialing a phone number, the time (in sec‐
onds) to wait for a connection to be established;
abbreviated dial. dialtimeout is initially set to 60
seconds, and can only changed by the super-user.

nect from it; abbreviated di. If the di capability is
present, disconnect is initially set to the value of
that capability. Otherwise, disconnect is set to a null
string ("").

transfer by waiting for the echo of the last character
transmitted; abbreviated ec. If the ec capability is
present, echocheck is initially set to on. Otherwise,
echocheck is initially set to off.

transmission during a ~< file transfer command; abbre‐
viated eofr. If the ie capability is present, eofread
is initially set to the value of that capability. Oth‐
erwise, eofread is set to a null string ("").
eofwrite (str) The string sent to indicate end-of-transmission
during a ~> file transfer command; abbreviated eofw. If
the oe capability is present, eofread is initially set
to the value of that capability. Otherwise, eofread is
set to a null string ("").
eol (str) The set of characters which indicate an end-of-
line. tip will recognize escape characters only after
an end-of-line. If the el capability is present, eol is
initially set to the value of that capability. Other‐
wise, eol is set to a null string ("").
escape (char) The command prefix (escape) character; abbrevi‐
ated es. If the es capability is present, escape is
initially set to the value of that capability. Other‐
wise, escape is set to '~'.
etimeout (num) The amount of time, in seconds, that tip should
wait for the echo-check response when echocheck is set;
abbreviated et. If the et capability is present, etime‐
out is initially set to the value of that capability.
Otherwise, etimeout is set to 10 seconds.
exceptions (str) The set of characters which should not be dis‐
carded due to the beautification switch; abbreviated
ex. If the ex capability is present, exceptions is ini‐
tially set to the value of that capability. Otherwise,
exceptions is set to '\t\n\f\b'.
force (char) The character used to force literal data trans‐
mission; abbreviated fo. If the fo capability is
present, force is initially set to the value of that
capability. Otherwise, force is set to \377 (which dis‐
ables it).
framesize (num) The amount of data (in bytes) to buffer between
file system writes when receiving files; abbreviated
fr. If the fs capability is present, framesize is ini‐
tially set to the value of that capability. Otherwise,
framesize is set to 1024.
halfduplex (bool) Do local echoing because the host is half-
duplex; abbreviated hdx. If the hd capability is
present, halfduplex is initially set to on. Otherwise,
halfduplex is initially set to off.
hardwareflow (bool) Do hardware flow control; abbreviated hf. If the
hf capability is present, hardwareflow is initially set
to on. Otherwise, hardwareflowcontrol is initially set
to off.
host (str) The name of the host to which you are connected;
abbreviated ho. host is permanently set to the name
given on the command line or in the HOST environment
variable.
localecho (bool) A synonym for halfduplex; abbreviated le.
log (str) The name of the file to which to log information
about outgoing phone calls. log is initially set to
/var/adm/aculog, and can only be inspected or changed
by the super-user.
parity (str) The parity to be generated and checked when talk‐
ing to the remote host; abbreviated par. The possible
values are:
none> Parity is not checked on input, and the parity
zero bit is set to zero on output.
one Parity is not checked on input, and the parity
bit is set to one on output.
even Even parity is checked for on input and gener‐
ated on output.
odd Odd parity is checked for on input and gener‐
ated on output.
If the pa capability is present, parity is initially
set to the value of that capability; otherwise, parity
is set to none.
phones The file in which to find hidden phone numbers. If the
environment variable PHONES is set, phones is set to
the value of PHONES. Otherwise, phones is set to
/etc/phones. The value of phones cannot be changed from
within tip.
prompt (char) The character which indicates an end-of-line on
the remote host; abbreviated pr. This value is used to
synchronize during data transfers. The count of lines
transferred during a file transfer command is based on
receipt of this character. If the pr capability is
present, prompt is initially set to the value of that
capability. Otherwise, prompt is set to \n.
raise (bool) Uppercase mapping mode; abbreviated ra. When
this mode is enabled, all lowercase letters will be
mapped to uppercase by tip for transmission to the
remote machine. If the ra capability is present, raise
is initially set to on. Otherwise, raise is initially
set to off.
raisechar (char) The input character used to toggle uppercase
mapping mode; abbreviated rc. If the rc capability is
present, raisechar is initially set to the value of
that capability. Otherwise, raisechar is set to \377
(which disables it).
rawftp (bool) Send all characters during file transfers; do
not filter non-printable characters, and do not do
translations like \n to \r. Abbreviated raw. If the rw
capability is present, rawftp is initially set to on.
Otherwise, rawftp is initially set to off.
record (str) The name of the file in which a session script is
recorded; abbreviated rec. If the re capability is
present, record is initially set to the value of that
capability. Otherwise, record is set to tip.record.

tems. If the environment variable REMOTE is set, remote
is set to the value of REMOTE. Otherwise, remote is set
to /etc/remote. The value of remote cannot be changed
from within tip.
script (bool) Session scripting mode; abbreviated sc. When
script is on, tip will record everything transmitted by
the remote machine in the script record file specified
in record. If the beautify switch is on, only printable
ASCII characters will be included in the script file
(those characters between 040 and 0177). The variable
exceptions is used to indicate characters which are an
exception to the normal beautification rules. If the sc
capability is present, script is initially set to on.
Otherwise, script is initially set to off.
tabexpand (bool) Expand TAB characters to SPACE characters during
file transfers; abbreviated tab. When tabexpand is on,
each tab is expanded to eight SPACE characters. If the
tb capability is present, tabexpand is initially set to
on. Otherwise, tabexpand is initially set to off.
tandem (bool) Use XON/XOFF flow control to limit the rate that
data is sent by the remote host; abbreviated ta. If the
nt capability is present, tandem is initially set to
off. Otherwise, tandem is initially set to on.
verbose (bool) Verbose mode; abbreviated verb; When verbose
mode is enabled, tip prints messages while dialing,
shows the current number of lines transferred during a
file transfer operations, and more. If the nv capabil‐
ity is present, verbose is initially set to off. Other‐
wise, verbose is initially set to on.
SHELL (str) The name of the shell to use for the ~! command;
default value is /bin/sh, or taken from the environ‐
ment.
HOME (str) The home directory to use for the ~c command.
Default value is taken from the environment.
