+     The attached document is the HELP file for the Utah-10
+implementation of the User FTP Process. This is what the user has
+typed on his console when he types 'HELP<cr>', and as such is the only
+documention produced to date.

+
+
+I. Control Characters
+
+      There are several control characters that have meaning to the FTP
+Process. First, the abort character is <control-z> (SUB), next for
+editing, only <control-r>, <control-a>, <control-h>, <control-v>,
+<control-w>, <alt-mode>, <eol>, <space>, <control-x> and <rub-out> have
+any meaning, <control-a> (SOH) and <control-h> (BS) are the character
+delete keys. <control-w> is the word delete character, Note: When dowing
+the ' funktion, this character will delete the entire line typed.
+<control-v> says take the next character literally. <alt-mode> (ESC)
+terminates the command giving helpful noise words, <eol> and <space> are
+terminators also. These last two will give no command completion or
+noise words. All three echo as a space however.  <control-x> (CAN) and
+<rub-out> (DEL) are the command abort characters. <control-r> (DC2) will
+retype the line as the command interpreter sees it. When using the ?  as
+a prompter, for initial commands, it will type-out all commands that
+begin with that particular character string.  If it is typed in a sub-
+command field, it will type out the prompt message only if it is the
+first character typed. At all other times, it will be accepted as part
+of the typed string.
+
+
+II. General Information
+
+      The FTP user process is designed to make transferring files from
+one host on the ARPANET to another much easier than it has been up until
+now. To this end, the command language was designed to be as natural as
+possible.
+
+      The command interpreter is, of course, part of this idea.
+Therefore, to help the user as much as possible, there are several ways
+to find out what is expected in the form of commands, file-names, user-
+names, etc. When the user has typed nothing, typing a ? will cause the
+interpreter to type out all the commands that are available to the user.
+If the user has typed anything at all, then it will respond with all
+commands that begin with the particular character string.
+
+      So that the command language was as easy to learn as possible, the
+command interpreter will 'see' nothing that is not part of a legal
+command. If the user types anything that is not expected, the character
+is not echoed and a bell is echoed instead.
+

+                                                                [Page 2]

+
+
+IV. Detailed Description of the Commands
+
+         The commands and their syntax are described in greater detail
+   blow. The words in parenthesis are noise words.  NOTE: upper and
+   lower case are identical. Unless otherwise noted in the command
+   description, all commands described are implemented.
+
+<host name> or <host number>
+   Performs the ICP to the indicated host with explanatory remarks if
+   the ICP is not possible.
+
+MODE <mode descriptor>
+   Sets the mode of the data transfer connection according to the
+   following sub-commandos:
+
+   STREAM: bit stream, end of file is indicated by the data connection
+   closing.
+
+   BLOCK: formats (or expects formatted) data into blocks.
+
+   TEXT: Sends or retreives text. Forces TYPE ASCII and BYTE 8. This
+   command sends the appropiate commands to the foreign host, then sends
+   the data using the TELNET codes for EOR and EOF as per the FTP
+   Protocol.
+
+   HASP: compress data.
+
+   NOTE: Of the above sub-commands, only MODE STREAM and MODE TEXT are
+   implemented at present.
+
+RETREIVE (file) <remote file> (to file) <local file name>
+   Sends the retr command to the remote server, sets up the data
+   connection according to any previous MODE, TYPE, BYTE commands. Puts
+   the data coming on the the data connection into the local file
+   specified.
+
+GET (file) <remote file name> (to file) <local file name>
+   See description of RETREIVE.
+
+STORE (local file) <file name> (onto file) <remote file>
+   Accepts a local file name, does the formatting according to any
+   previous BYTE, TYPE, MODE commands and sends it to the foreign host.
+
+SEND (local file) <file name> (onto file) <remote file>
+   See description of STORE.
+
+APPEND (local file) <file name> (to remote file) <remote file>
+   Does the same as a store except that the file is appended to the
+
+
+
+                                                                [Page 4]
+
+User FTP Documentation                          Detailed Command Listing
+
+
+   remote file rather that just writing over the file.
+
+RENAME (existing file) <file name> (to be) <new file name>
+   Accepts the name of n old remote file and asks for a new file name,
+   sends the appropiate commands and names to the foreign host causing
+   the old file name to be replaced by the new file name.
+
+DELETE (file) <file name>
+   This command causes the remote file to be marked for deletion. It
+   does require that the command be confirmed twice.
+
+BYE
+   Takes no arguments. Causes the server to terminate the current
+   session with the user. The program will return to the EXEC MODE when
+   the command has been acknowledged by the remote server.
+
+COPY
+   This command does a variety of things. First. it allows the user do
+   describe a file group. EG: *.mac, *.sav, etc.  The *'s may be for
+   foreign files or local files according to the following sub-commands:
+
+  REMOTE (remote file group) <remote file grouping>:
+   Causes the user FTP to ask the server for the file in <remote file
+   grouping>. Then asks the user to specify where each file is to go. A
+   typical sequence might look like the following:
+
+   !copy remote (remote file group) ftp.*
+   Please be patient. Getting remote file names.
+   Got them.
+   !copy (file) <HICKS>FTP.MAC;| (to file) ftp.mac [New file]
+   [Messages and etc. follow with the above line being
+   repeated for each file in the remote file group.]
+
+  LOCAL (local file grouping) <local file group>:
+   Causes the user FTP to accept the file group specified, and send the
+   file names to the server leaving off the <directory name> and version
+   number of the local file. The user may not specify *'d devices of *'d
+   directorys. A line for this might look like the following:
+   !copy local (local file group) ftp.*;*
+    [Confirm]
+
+   Next, if the user does not specify any *'s for either the remote file
+   or the local file, this command is exactly like the RETREIVE or STORE
+   command described earlier.
+LOGOUT
+   Takes no arguments. See description of BYE command for more details.
+
+
+
+
+
+                                                                [Page 5]
+
+User FTP Documentation                          Detailed Command Listing
+
+
+RESET
+   Takes no arguments. Causes the user process to close all connections
+   (if necessary), all files (if necessary), and reset the programs
+   parameters to their defaults.
+
+DDT
+   If DDT is loaded, just starts DDT. If DDT is not loaded, it will load
+   DDT and then start it at its initial start-up location.  This command
+   will casue an abnormal interrupt if DDT is not found.
+
+LIST (file group) <remote file group> (to file) <local file>
+   Esentially causes the remote server to do a directory command. The
+   default is *.* and since the listing will come on the data connection,
+   the user must specify a local file. A sample line might look like the
+   following: !list (file group) *.* (going to file) tty: [ok]
+
+SOCKET <socket descriptor>
+   Will accept a socket descriptor for the data to go to or come from. At
+   present it is NOT IMPLEMENTED because we have not decided on the
+   format of the command to the server.
+
+ALLOCATE <decimal number of bytes>
+   Accepts as its argument a decimal number of bytes (of the specified
+   size) telling the server how many bytes of storage to reserve for the
+   next store of append.
+
+QUIT
+   Takes no arguments. Returns the console to the EXEC. The program may
+   be continued with no harm done.
+
+   This command allows the user to send arbitrary strings to the remote
+   server. At present, when talking to a TENEX site, it is only useful
+   for doing the 'MAIL' command.  Other sites may have help commands of
+   whatever.
+
+HOST <ARPANET host name of number>
+   Allows the user to specify an ARPANET host without actually connecting
+   to the host. This specified host will be the ont that is connected to
+   (or the attempt will be made anyway) when the next 'immediate' command
+   is executed. EG: LOGIN, RETREIVE, STORE, LIST, etc.
+
+USER (name is) <remote user's name>
+   Sets the user name for the remote system. Useful for systems that
+   require no password for the specified name.  Does nothing until an
+   user must be 'logged into' the remote system. The programm knows this
+   and so will not let the user execute any commands (RETREIVE, STORE,
+   APPEND, LIST, STATUS, RENAME, DELETE) until he has at least specified
+   a remote user name. The LOGIN command does this as does this command.
+
+
+
+                                                                [Page 6]
+
+User FTP Documentation                          Detailed Command Listing
+
+
+STATUS (of the) <sub-cmd> (at host) <ARPANET host>
+   Accepts as its argument one of the following sub-commands:
+  SERVICE (at host) <ARPANET host name or number>: Attempts to
+   perform the ICP to the specified host. Does not disturb any existing
+   connections.
+  <ARPANET host name or number>: See description of STATUS SERVICE
+  above.
+
+  STATUS (of file) <remote file group>: Similar to the LIST
+   command described above except that the listing does not gone back on
+   the data connection but on the TELNET connection. See LIST command for
+   more details.
+  <COMMAND-TERMINATOR>: Just sneds the STAT command.
+   Typically, is good for finding out where your are and perhaps who you
+   are.
+
+PASSWORD (is) <passowrd for remote user's name>
+   Sets the password for the remote user's name. It is NOT echoed and
+   does nothing until the next 'immediate' command is executed.
+
+ACCOUNT (is) <account number or string>
+   Accepts a string of number that can be charged for any activity the
+   user specifies. EG: STORE, RETREIVE or APPEND. Useful only for systems
+   that require this information of course. Also does nothing until the
+   next immediate command is executed.
+
+LOGIN <user name> <password> <optional account>
+   the format of this command is identical to the TENEX login command. It
+   accepts a user name, password, and an optional account number. If no
+   host has been specified, it will ask for the host to be connected to.
+   This command will cause the ICP to take place if necessary.
+
+BYTE (size is) <decimal byte size>
+   This command sets the byte size for the data connection.  The default
+   byte size is 8 bytes.
+
+Type (is) <type descriptor>
+   Takes as its argument one of the following subcommands:
+  TENEX: Shorthand that sets TYPE IMAGE and BYTE 36.
+  EBCDIC: Says that the data will be Ebcdic.
+  PRINT: Says that the data is an Ascii print file with ASA vertical
+   format controls.
+  LOCAL: Forces the user and server FTP to accept whatever
+   byte size the user has specified. For the present, this type is
+   treated the same as for IMAGE TYPE.
+  IMAGE: Does the same as LOCAL. Just forces the user and server FTP to
+   accept the specified byte size without doing any translation as is
+   done for ASCII type. For most efficient usage of this command, the
+
+
+
+                                                                [Page 7]
+
+User FTP Documentation                          Detailed Command Listing
+
+
+   matching byte size should be BYTE 36 when using TENEX sites as
+   servers.
+  ASCII: Sets TYPE ASCII and 8 bit bytes. Useful for text files.
+   NOTE: Of the above sub-commands, only PRINT and EBCDIC are not
+   implemented yet.
+
+STRUCTURE (is) <file structure descriptor>
+   Accepts as its argument one of the following sub-commands:
+  REDORD: Says the data on the data connection has record
+   structure information contained in it. NOTE: Since TENEX NOT support
+   record structured files per se, this mode only useful for sending text
+   files to or retreiving text files from non-TENEX sites. The <EOL> in
+   these files is converted to the TELNET EOR code for transmission and
+   EOR to <EOL> etc. for reception.
+
+  File: Says the data stream has no record structure information in it.
+
+TENEX
+   See description under TYPE TENEX.
+
+ASCII
+   See description under TYPE ASCII.
+
+VERBOSE
+   This command sets the command completion/no completion flag. The
+   program assumes the NO VERBOSE mode and thus does not complete
+   commands when <space> or <eol> is used as a command terminator It also
+   causes the noise words to be typed if in the verbose mode.
