14 Tip and cu establish a full-duplex connection to another machine, giv‐
15 ing the appearance of being logged in directly on the remote cpu. It
16 goes without saying that you must have a login on the machine (or
17 equivalent) to which you wish to connect. The preferred interface is
18 tip. The cu interface is included for those people attached to the
19 ``call UNIX'' command of version 7. This manual page describes only
20 tip.
21 Typed characters are normally transmitted directly to the remote
23 machine (which does the echoing as well). A tilde (`~') appearing as
24 the first character of a line is an escape signal; the following are
25 recognized:
26 ~^D ~. Drop the connection and exit (you may still be logged in on
28 the remote machine).
29 ~c [name]
31 Change directory to name (no argument implies change to your
32 home directory).
33 ~! Escape to a shell (exiting the shell will return you to tip).
35 ~> Copy file from local to remote. Tip prompts for the name of
37 a local file to transmit.
38 ~< Copy file from remote to local. Tip prompts first for the
40 name of the file to be sent, then for a command to be exe‐
41 cuted on the remote machine.
42 ~p from [ to ]
44 Send a file to a remote UNIX host. The put command causes
45 the remote UNIX system to run the command string ``cat >
46 'to''', while tip sends it the ``from'' file. If the ``to''
47 file isn't specified the ``from'' file name is used. This
48 command is actually a UNIX specific version of the ``~>''
49 command.
50 ~t from [ to ]
52 Take a file from a remote UNIX host. As in the put command
53 the ``to'' file defaults to the ``from'' file name if it
54 isn't specified. The remote host executes the command string
55 ``cat 'from';echo ^A'' to send the file to tip.
56 ~| Pipe the output from a remote command to a local UNIX
58 process. The command string sent to the local UNIX system is
59 processed by the shell.
60 ~$ Pipe the output from a local UNIX process to the remote host.
62 The command string sent to the local UNIX system is processed
63 by the shell.
64 ~# Send a BREAK to the remote system. For systems which don't
66 support the necessary ioctl call the break is simulated by a
67 sequence of line speed changes and DEL characters.
68 ~s Set a variable (see the discussion below).
70 ~^Z Stop tip (only available with job control).
72 ~^Y Stop only the ``local side'' of tip (only available with job
74 control); the ``remote side'' of tip, the side that displays
75 output from the remote host, is left running.
76 ~? Get a summary of the tilde escapes
78 Tip uses the file /etc/remote to find how to reach a particular system
81 and to find out how it should operate while talking to the system;
82 refer to remote(5) for a full description. Each system has a default
83 baud rate with which to establish a connection. If this value is not
84 suitable, the baud rate to be used may be specified on the command
85 line, e.g. ``tip -300 mds''.
86 When tip establishes a connection it sends out a connection message to
88 the remote system; the default value, if any, is defined in
89 /etc/remote.
90 When tip prompts for an argument (e.g. during setup of a file transfer)
92 the line typed may be edited with the standard erase and kill charac‐
93 ters. A null line in response to a prompt, or an interrupt, will abort
94 the dialogue and return you to the remote machine.
95 Tip guards against multiple users connecting to a remote system by
97 opening modems and terminal lines with exclusive access, and by honor‐
98 ing the locking protocol used by uucp(1C).
99 During file transfers tip provides a running count of the number of
101 lines transferred. When using the ~> and ~< commands, the ``eofread''
102 and ``eofwrite'' variables are used to recognize end-of-file when read‐
103 ing, and specify end-of-file when writing (see below). File transfers
104 normally depend on tandem mode for flow control. If the remote system
105 does not support tandem mode, ``echocheck'' may be set to indicate tip
106 should synchronize with the remote system on the echo of each transmit‐
107 ted character.
108 When tip must dial a phone number to connect to a system it will print
110 various messages indicating its actions. Tip supports the DEC DN-11
111 and Racal-Vadic 831 auto-call-units; the DEC DF02 and DF03, Ventel
112 212+, Racal-Vadic 3451, and Bizcomp 1031 and 1032 integral call
113 unit/modems.
114 VARIABLES
116 Tip maintains a set of variables which control its operation. Some of
118 these variable are read-only to normal users (root is allowed to change
119 anything of interest). Variables may be displayed and set through the
120 ``s'' escape. The syntax for variables is patterned after vi(1) and
121 Mail(1). Supplying ``all'' as an argument to the set command displays
122 all variables readable by the user. Alternatively, the user may
123 request display of a particular variable by attaching a `?' to the end.
124 For example ``escape?'' displays the current escape character.
125 Variables are numeric, string, character, or boolean values. Boolean
127 variables are set merely by specifying their name; they may be reset by
128 prepending a `!' to the name. Other variable types are set by concate‐
129 nating an `=' and the value. The entire assignment must not have any
130 blanks in it. A single set command may be used to interrogate as well
131 as set a number of variables. Variables may be initialized at run time
132 by placing set commands (without the ``~s'' prefix in a file .tiprc in
133 one's home directory). The -v option causes tip to display the sets as
134 they are made. Certain common variables have abbreviations. The fol‐
135 lowing is a list of common variables, their abbreviations, and their
136 default values.
137 beautify
139 (bool) Discard unprintable characters when a session is being
140 scripted; abbreviated be.
141 baudrate
143 (num) The baud rate at which the connection was established;
144 abbreviated ba.
145 dialtimeout
147 (num) When dialing a phone number, the time (in seconds) to wait
148 for a connection to be established; abbreviated dial.
149 echocheck
151 (bool) Synchronize with the remote host during file transfer by
152 waiting for the echo of the last character transmitted; default
153 is off.
154 eofread
156 (str) The set of characters which signify and end-of-tranmission
157 during a ~< file transfer command; abbreviated eofr.
158 eofwrite
160 (str) The string sent to indicate end-of-transmission during a
161 ~> file transfer command; abbreviated eofw.
162 eol
164 (str) The set of characters which indicate an end-of-line. Tip
165 will recognize escape characters only after an end-of-line.
166 escape
168 (char) The command prefix (escape) character; abbreviated es;
169 default value is `~'.
170 exceptions
172 (str) The set of characters which should not be discarded due to
173 the beautification switch; abbreviated ex; default value is
174 ``\t\n\f\b''.
175 force
177 (char) The character used to force literal data transmission;
178 abbreviated fo; default value is `^P'.
179 framesize
181 (num) The amount of data (in bytes) to buffer between file sys‐
182 tem writes when receiving files; abbreviated fr.
183 host
185 (str) The name of the host to which you are connected; abbrevi‐
186 ated ho.
187 prompt
189 (char) The character which indicates and end-of-line on the
190 remote host; abbreviated pr; default value is `\n'. This value
191 is used to synchronize during data transfers. The count of
192 lines transferred during a file transfer command is based on
193 recipt of this character.
194 raise
196 (bool) Upper case mapping mode; abbreviated ra; default value is
197 off. When this mode is enabled, all lower case letters will be
198 mapped to upper case by tip for transmission to the remote
199 machine.
200 raisechar
202 (char) The input character used to toggle upper case mapping
203 mode; abbreviated rc; default value is `^A'.
204 record
206 (str) The name of the file in which a session script is
207 recorded; abbreviated rec; default value is ``tip.record''.
208 script
210 (bool) Session scripting mode; abbreviated sc; default is off.
211 When script is true, tip will record everything transmitted by
212 the remote machine in the script record file specified in
213 record. If the beautify switch is on, only printable ASCII
214 characters will be included in the script file (those characters
215 betwee 040 and 0177). The variable exceptions is used to indi‐
216 cate characters which are an exception to the normal beautifica‐
217 tion rules.
218 tabexpand
220 (bool) Expand tabs to spaces during file transfers; abbreviated
221 tab; default value is false. Each tab is expanded to 8 spaces.
222 verbose
224 (bool) Verbose mode; abbreviated verb; default is true. When
225 verbose mode is enabled, tip prints messages while dialing,
226 shows the current number of lines transferred during a file
227 transfer operations, and more.
228 SHELL
230 (str) The name of the shell to use for the ~! command; default
231 value is ``/bin/sh'', or taken from the environment.
232 HOME
234 (str) The home directory to use for the ~c command; default
235 value is taken from the environment.
