2252a1c0 | 43 | .I Tip |
2057e373 | 44 | and |
2252a1c0 KM |
45 | .I cu |
46 | establish a full-duplex connection to another machine, | |
47 | giving the appearance of being logged in directly on the | |
48 | remote cpu. It goes without saying that you must have a login | |
49 | on the machine (or equivalent) to which you wish to connect. | |
50 | The preferred interface is | |
51 | .IR tip . | |
52 | The | |
53 | .I cu | |
54 | interface is included for those people attached to the | |
55 | ``call UNIX'' command of version 7. This manual page | |
56 | describes only | |
57 | .IR tip . | |

59 | Typed characters are normally transmitted directly to the remote |
60 | machine (which does the echoing as well). A tilde (`~') appearing | |
61 | as the first character of a line is an escape signal; the following | |
62 | are recognized: | |
63 | .TP 10 | |
64 | .B ~^D ~. | |
65 | Drop the connection and exit | |
66 | (you may still be logged in on the | |
67 | remote machine). | |
68 | .TP 10 | |
69 | \fB~c \fP [\fIname\fP] | |
70 | Change directory to name (no argument | |
71 | implies change to your home directory). | |
72 | .TP 10 | |
73 | .B ~! | |
74 | Escape to a shell (exiting the shell will | |
75 | return you to tip). | |
76 | .TP 10 | |
77 | .B ~> | |
78 | Copy file from local to remote. | |
79 | .I Tip | |
80 | prompts for the name of a local file to transmit. | |
81 | .TP 10 | |
82 | .B ~< | |
83 | Copy file from remote to local. | |
84 | .I Tip | |
85 | prompts first for the name of the file to be sent, then for | |
86 | a command to be executed on the remote machine. | |
87 | .TP 10 | |
88 | \fB~p\fP \fIfrom\fP [ \fIto\fP ] | |
89 | Send a file to a remote UNIX host. The put command causes the remote UNIX | |
90 | system to run the command string ``cat > 'to''', while | |
91 | .I tip | |
92 | sends it the ``from'' | |
93 | file. If the ``to'' file isn't specified the ``from'' file name is used. | |
94 | This command is actually a UNIX specific version of the ``~>'' command. | |
95 | .TP 10 | |
96 | \fB~t\fP \fIfrom\fP [ \fIto\fP ] | |
97 | Take a file from a remote UNIX host. | |
98 | As in the put command the ``to'' file | |
99 | defaults to the ``from'' file name if it isn't specified. | |
100 | The remote host | |
101 | executes the command string ``cat 'from';echo ^A'' to send the file to | |
102 | .IR tip . | |
103 | .TP 10 | |
104 | .B ~| | |
105 | Pipe the output from a remote command to a local UNIX process. | |
106 | The command string sent to the local UNIX system is processed by the shell. | |
107 | .TP 10 | |
52f09821 DS |
108 | .B ~$ |
109 | Pipe the output from a local UNIX process to the remote host. | |
110 | The command string sent to the local UNIX system is processed by the shell. | |
111 | .TP 10 | |
2252a1c0 KM |
112 | .B ~# |
113 | Send a BREAK to the remote system. | |
114 | For systems which don't support the | |
115 | necessary | |
116 | .I ioctl | |
117 | call the break is simulated by a sequence of line speed changes | |
118 | and DEL characters. | |
119 | .TP 10 | |
120 | .B ~s | |
121 | Set a variable (see the discussion below). | |
122 | .TP 10 | |
123 | .B ~^Z | |
124 | Stop | |
125 | .I tip | |
126 | (only available with job control). | |
127 | .TP 10 | |
c6f7764d SL |
128 | .B ~^Y |
129 | Stop only the ``local side'' of | |
130 | .I tip | |
131 | (only available with job control); | |
132 | the ``remote side'' of | |
133 | .IR tip , | |
134 | the side that displays output from the remote host, is left running. | |
135 | .TP 10 | |

2252a1c0 KM |
140 | .I Tip |
141 | uses the file /etc/remote to find how to reach a particular | |
142 | system and to find out how it should operate while talking | |
143 | to the system; | |
144 | refer to | |
145 | .IR remote (5) | |
146 | for a full description. | |
147 | Each system has a default baud rate with which to | |
148 | establish a connection. If this value is not suitable, the baud rate | |
149 | to be used may be specified on the command line, e.g. ``tip -300 mds''. | |
2057e373 | 150 | .PP |
2252a1c0 KM |
151 | When |
152 | .I tip | |
153 | establishes a connection it sends out a | |
154 | connection message to the remote system; the default value, if any, | |
155 | is defined in /etc/remote. | |
2057e373 | 156 | .PP |
2252a1c0 KM |
157 | When |
158 | .I tip | |
159 | prompts for an argument (e.g. during setup of | |
160 | a file transfer) the line typed may be edited with the standard | |
161 | erase and kill characters. A null line in response to a prompt, | |
162 | or an interrupt, will abort the dialogue and return you to the | |
163 | remote machine. | |
2057e373 | 164 | .PP |
2252a1c0 KM |
165 | .I Tip |
166 | guards against multiple users connecting to a remote system | |
167 | by opening modems and terminal lines with exclusive access, | |
168 | and by honoring the locking protocol used by | |
169 | .IR uucp (1C). | |
2057e373 | 170 | .PP |
2252a1c0 KM |
171 | During file transfers |
172 | .I tip | |
173 | provides a running count of the number of lines transferred. | |
174 | When using the ~> and ~< commands, the ``eofread'' and ``eofwrite'' | |
175 | variables are used to recognize end-of-file when reading, and | |
176 | specify end-of-file when writing (see below). File transfers | |
177 | normally depend on tandem mode for flow control. If the remote | |
178 | system does not support tandem mode, ``echocheck'' may be set | |
179 | to indicate | |
180 | .I tip | |
181 | should synchronize with the remote system on the echo of each | |
182 | transmitted character. | |
2057e373 | 183 | .PP |
2252a1c0 KM |
184 | When |
185 | .I tip | |
186 | must dial a phone number to connect to a system it will print | |
187 | various messages indicating its actions. | |
188 | .I Tip | |
189 | supports the DEC DN-11 and Racal-Vadic 831 auto-call-units; | |
190 | the DEC DF02 and DF03, Ventel 212+, Racal-Vadic 3451, and | |
191 | Bizcomp 1031 and 1032 integral call unit/modems. | |

2057e373 | 195 | .PP |
2252a1c0 KM |
196 | .I Tip |
197 | maintains a set of | |
198 | .I variables | |
199 | which control its operation. | |
200 | Some of these variable are read-only to normal users (root is allowed | |
201 | to change anything of interest). Variables may be displayed | |
202 | and set through the ``s'' escape. The syntax for variables is patterned | |
203 | after | |
204 | .IR vi (1) | |
2057e373 | 205 | and |
2252a1c0 KM |
206 | .IR Mail (1). |
207 | Supplying ``all'' | |
208 | as an argument to the set command displays all variables readable by | |
209 | the user. Alternatively, the user may request display of a particular | |
210 | variable by attaching a `?' to the end. For example ``escape?'' | |
211 | displays the current escape character. | |
2057e373 | 212 | .PP |
2252a1c0 KM |
213 | Variables are numeric, string, character, or boolean values. Boolean |
214 | variables are set merely by specifying their name; they may be reset | |
215 | by prepending a `!' to the name. Other variable types are set by | |
216 | concatenating an `=' and the value. The entire assignment must not | |
217 | have any blanks in it. A single set command may be used to interrogate | |
218 | as well as set a number of variables. | |
219 | Variables may be initialized at run time by placing set commands | |
220 | (without the ``~s'' prefix in a file | |
221 | .I .tiprc | |
222 | in one's home directory). The | |
223 | .B \-v | |
224 | option causes | |
225 | .I tip | |
226 | to display the sets as they are made. | |
227 | Certain common variables have abbreviations. | |
228 | The following is a list of common variables, | |
229 | their abbreviations, and their default values. | |
