2: .SH NAME
3: kermit \- kermit file transfer
4: .SH SYNOPSIS
5: .B kermit
6: [ option ...] [file ...]
7: .SH DESCRIPTION
8: .I Kermit
9: is a file transfer program that allows files to be moved
10: between machines of many different operating systems and architectures.
11: This man page describes version 4C of the program.
12: .PP
13: Arguments are optional. If
14: .I Kermit
15: is executed without arguments, it will enter command mode. Otherwise,
16: .I kermit
17: will read the arguments off the command line and interpret them.
18: .RE 1
19: .PP
20: The following notation is used in command descriptions:
21: .RE 1
22: .TP 8
23: .I fn
24: A Unix file specification, possibly containing either of the "wildcard"
25: characters '*' or '?' ('*' matches all character strings, '?' matches
26: any single character).
27: .TP
28: .I fn1
29: A Unix file specification which may not contain '*' or '?'.
30: .TP
31: .I rfn
32: A remote file specification in the remote system's own syntax, which may
33: denote a single file or a group of files.
34: .TP
35: .I rfn1
36: A remote file specification which should denote only a single file.
37: .TP
38: .I n
39: A decimal number between 0 and 94.
40: .TP
41: .I c
42: A decimal number between 0 and 127 representing the value of an ASCII
43: character.
44: .TP
45: .I cc
46: A decimal number between 0 and 31, or else exactly 127, representing the
47: value of an ASCII control character.
48: .TP
49: .B [ ]
50: Any field in square braces is optional.
51: .TP
52: {\fIx,y,z\fR}
53: Alternatives are listed in curly braces.
54: .RE 1
55: .PP
56: .I Kermit
57: command line options may specify either actions or settings. If
58: .I Kermit
59: is invoked with a command line that specifies no actions, then it will
60: issue a prompt and begin interactive dialog. Action options specify
61: either protocol transactions or terminal connection.
62: .RE
63: .SS COMMAND LINE OPTIONS
64: .TP 8
65: .BI \-s " fn"
66: Send the specified file or files. If
67: .I fn
68: contains wildcard (meta) characters, the Unix shell expands it into a
69: list. If
70: .I fn
71: is '-' then
72: .I Kermit
73: sends from standard input, which must come from a file:
74: .sp 0.6v
75: kermit -s - < foo.bar
76: .sp 0.6v
77: or a parallel process:
78: .sp 0.6v
79: ls -l | kermit -s -
80: .IP
81: You cannot use this mechanism to send terminal typein. If you want to
82: send a file whose name is "-" you can precede it with a path name, as in
83: .sp 0.6v
84: kermit -s ./-
85: .TP
86: .B \-r
87: Receive a file or files. Wait passively for files to arrive.
88: .TP
89: .B \-k
90: Receive (passively) a file or files, sending them to standard output.
91: This option can be used in several ways:
92: .sp 0.6v
93: kermit -k
94: .IP
95: Displays the incoming files on your screen; to be used only in "local
96: mode" (see below).
97: .sp 0.6v
98: kermit -k > fn1
99: .IP
100: Sends the incoming file or files to the named file,
101: .I fn1.
102: If more than
103: one file arrives, all are concatenated together into the single file
104: .I fn1.
105: .sp 0.6v
106: kermit -k | command
107: .IP
108: Pipes the incoming data (single or multiple files) to the indicated
109: command, as in
110: .sp 0.6v
111: kermit -k | sort > sorted.stuff
112: .TP
113: .BI \-a " fn1"
114: If you have specified a file transfer option, you may specify an
115: alternate name for a single file with the
116: .B -a
117: option. For example,
118: .sp 0.6v
119: kermit -s foo -a bar
120: .IP
121: sends the file foo telling the receiver that its name is bar. If more
122: than one file arrives or is sent, only the first file is affected by the
123: .B \-a
124: option:
125: .sp 0.6v
126: kermit -ra baz
127: .IP
128: stores the first incoming file under the name baz.
129: .TP
130: .B \-x
131: Begin server operation. May be used in either local or remote mode.
132: .RE 1
133: .PP
134: Before proceeding, a few words about remote and local operation are necessary.
135: .I Kermit
136: is "local" if it is running on a PC or workstation that you are using
137: directly, or if it is running on a multiuser system and transferring
138: files over an external communication line \(em not your job's controlling
139: terminal or console.
140: .I Kermit
141: is remote if it is running on a multiuser system and transferring files
142: over its own controlling terminal's communication line, connected to
143: your PC or workstation.
144: .PP
145: If you are running
146: .I Kermit
147: on a PC, it is in local mode by default, with the "back port" designated
148: for file transfer and terminal connection. If you are running
149: .I Kermit
150: on a multiuser (timesharing) system, it is in remote mode unless you
151: explicitly point it at an external line for file transfer or terminal
152: connection. The following command sets
153: .IR Kermit 's
154: "mode":
155: .RE 1
156: .TP 8
157: .BI \-l " dev"
158: Line \(em Specify a terminal line to use for file transfer and terminal
159: connection, as in
160: .sp 0.6v
161: kermit -l /dev/ttyi5
162: .RE 1
163: .PP
164: When an external line is being used, you might also need some additional
165: options for successful communication with the remote system:
166: .TP
167: .BI \-b " n"
168: Baud \(em Specify the baud rate for the line given in the
169: .B \-l
170: option, as in
171: .sp 0.6v
172: kermit -l /dev/ttyi5 -b 9600
173: .IP
174: This option should always be included with the
175: .B \-l
176: option, since the speed of an external line is not necessarily what you
177: expect.
178: .TP
179: .BI \-p " x"
180: Parity \(em
181: .BR e ,
182: .BR o ,
183: .BR m ,
184: .BR s ,
185: .B n
186: (even, odd, mark, space, or none). If parity is other than none, then
187: the 8th-bit prefixing mechanism will be used for transferring 8-bit
188: binary data, provided the opposite
189: .I Kermit
190: agrees. The default parity is none.
191: .TP
192: .B \-t
193: Specifies half duplex, line turnaround with XON as the handshake
194: character.
195: .RE 1
196: .PP
197: The following commands may be used only with a
198: .I Kermit
199: which is local \(em either by default or else because the
200: .B \-l
201: option has been specified.
202: .TP 8
203: .BI \-g " rfn"
204: Actively request a remote server to send the named file or files;
205: .I rfn
206: is a file specification in the remote host's own syntax. If
207: .I fn
208: happens to contain any special shell characters, like '*', these must be
209: quoted, as in
210: .sp 0.6v
211: kermit -g x\\*.\\?
212: .TP
213: .B \-f
214: Send a 'finish' command to a remote server.
215: .TP
216: .B \-c
217: Establish a terminal connection over the specified or default
218: communication line, before any protocol transaction takes place. Get
219: back to the local system by typing the escape character (normally
220: Control-Backslash) followed by the letter 'c'.
221: .TP
222: .B \-n
223: Like
224: .B \-c,
225: but after a protocol transaction takes place;
226: .B \-c
227: and
228: .B \-n
229: may both be used in the same command. The use of
230: .B \-n
231: and
232: .B \-c
233: is illustrated below.
234: .RE 1
235: .PP
236: On a timesharing system, the
237: .B \-l
238: and
239: .B \-b
240: options will also have to be included with the
241: .BR \-r ,
242: .BR \-k ,
243: or
244: .B \-s
245: options if the other
246: .I Kermit
247: is on a remote system.
248: .PP
249: If
250: .I kermit
251: is in local mode, the screen (stdout) is continously updated to show the
252: progress of the file transer. A dot is printed for every four data
253: packets, other packets are shown by type (e.g. 'S' for Send-Init), 'T'
254: is printed when there's a timeout, and '%' for each retransmission. In
255: addition, you may type (to stdin) certain "interrupt" commands during
256: file transfer:
257: .IP
258: Control-F: Interrupt the current File, and go on to the next (if any).
259: .IP
260: Control-B: Interrupt the entire Batch of files, terminate the transaction.
261: .IP
262: Control-R: Resend the current packet
263: .IP
264: Control-A: Display a status report for the current transaction.
265: .RE
266: .IP
267: These interrupt characters differ from the ones used in other
268: .I Kermit
269: implementations to avoid conflict with Unix shell interrupt characters.
270: With System III and System V implementations of Unix, interrupt commands
271: must be preceeded by the escape character (e.g. control-\\).
272: .RE
273: .PP
274: Several other command-line options are provided:
275: .TP 8
276: .B \-i
277: Specifies that files should be sent or received exactly "as is" with no
278: conversions. This option is necessary for transmitting binary files.
279: It may also be used to slightly boost efficiency in Unix-to-Unix
280: transfers of text files by eliminating CRLF/newline conversion.
281: .TP
282: .B \-w
283: Write-Protect \(em Avoid filename collisions for incoming files.
284: .TP
285: .B \-q
286: Quiet \(em Suppress screen update during file transfer, for instance to
287: allow a file transfer to proceed in the background.
288: .TP
289: .B \-d
290: Debug \(em Record debugging information in the file debug.log in the
291: current directory. Use this option if you believe the program is
292: misbehaving, and show the resulting log to your local

295: .TP
296: .B \-h
297: Help \(em Display a brief synopsis of the command line options.
298: .RE 1

300: The command line may contain no more than one protocol action option.
301: .SS INTERACTIVE OPERATION
302: .RE 1
303: .PP
304: .IR Kermit 's
305: interactive command prompt is "C-Kermit>". In response to this prompt,
306: you may type any valid command.
307: .I Kermit
308: executes the command and then prompts you for another command. The
309: process continues until you instruct the program to terminate.
310: .PP
311: Commands begin with a keyword, normally an English verb, such as "send".
312: You may omit trailing characters from any keyword, so long as you
313: specify sufficient characters to distinguish it from any other keyword
314: valid in that field. Certain commonly-used keywords (such as "send",
315: "receive", "connect") have special non-unique abbreviations ("s" for
316: "send", "r" for "receive", "c" for "connect").
317: .PP
318: Certain characters have special functions in interactive commands:
319: .PP
320: .TP 8
321: .B ?
322: Question mark, typed at any point in a command, will produce a message
323: explaining what is possible or expected at that point. Depending on the
324: context, the message may be a brief phrase, a menu of keywords, or a
325: list of files.
326: .TP 8
327: .B ESC
328: (The Escape or Altmode key) \(em Request completion of the current keyword

362: .RE 1
363: .PP
364: You may type the editing characters (DEL, ^W, etc) repeatedly, to delete
365: all the way back to the prompt. No action will be performed until the

373: Interactive
374: .I Kermit
375: accepts commands from files as well as from the keyboard. When you
376: enter interactive mode,
377: .I Kermit
378: looks for the file .kermrc in your home or current directory (first it
379: looks in the home directory, then in the current one) and executes any
380: commands it finds there. These commands must be in interactive format,
381: not Unix command-line format. A "take" command is also provided for use
382: at any time during an interactive session. Command files may be nested
383: to any reasonable depth.
