Kermit Software Source Code Archive - Web Access

Frank da Cruz
Page created:   September 2011
Most recent update:   Sat Apr 15 09:11:57 2023

Go straight to software archive table ]    [ NEW: DECSYSTEM-20 TOPS-20 Kermit 5.3(285), June 2023 ]

UPDATE FEBRUARY 2022: Cross-domain file downloads from HTTP sites are no longer allowed by browsers such and Firefox and Chrome; thus most of the links on this page no longer work because they go to the Kermit software archive at Columbia University, which is not yet an HTTPS site. To download old Kermit software from the Kermit archive, CLICK HERE to visit the original archive at Columbia. When Columbia converts the original Kermit site to HTTPS, downloads from outside will work again. The newer items in this archive (the one you are looking at) — the ones with a pale green background — can be downloaded direct from here. CLICK HERE to see if Columbia's Kermit project has been converted to HTTPS.

UPDATE APRIL-AUGUST 2021: Firefox and Chrome dropped support for FTP links. In October, Columbia University (where most of the archive resides) retired its FTP server. Fortunately, the links in the Tar.gz and Zip columns below are HTTP/HTTPS, not FTP, so they were not affected. Since we can't count on FTP any more, and since HTTP links can't produce file lists, and since many of the FTP links go to the Kermit software archive at Columbia University which has discontinued FTP service, I wrote a Kermit script to produce the same effect. Now, when you click on "file list" in any of the entries below, you should see a file list with clickable filenames, and when you click on a filename, you see (or download) the file. Each of the 189 new file lists is a web page that was built by the Kermit script. As of 2 May, the remaining 70 ftp links (to individual files or to Panix-resident file groups) have also been replaced. As of 31 August 2021, (hopefully) all of the links in the file lists display the list on your screen as you'd expect, instead of giving you a dialog to specify a "helper app".

This is a newer version of the Kermit software archive page at Columbia University. 99% of the links still go to Columbia's archive, but anything new since 2011 is also reflected here on this page, with links going to kermitproject.org; these new additions show up with a  pale green background , CLICK HERE for a summary of the new additions.

Welcome to what might be the biggest collection on earth of software source code for implementations of the same program on different computers and operating systems in different programming languages. This page provides, for the first time, convenient Web (HTTP) access to all the programs in the Kermit software archive. Each program can be downloaded as either a “tarball” (gzip'd tar archive for Unix) or a Zip archive (for Windows, VMS, and other platforms that have Unzip), and you can also look at or download individual files by clicking on "file list". In many cases manuals are also available, sometimes as PDF, others as plain text.

The once-common '.doc' and '.hlp' extensions that were used for plain-text-file have been converted (foo.doc → foodoc.txt; foo.hlp → foohlp.txt) to avoid unwanted invocations of Microsoft Word or Help programs; others have been left as they were. Here are some common ones:

.txt Text Plain text
.ann Announcement Plain text announcing a software release
.hlp Help Plain text (a short help file)
.doc Documentation Plain text (longer, e.g. a user manual)
.msg Message E-Mail message, plain text
.bwr Beware Hints and tips, plain text
.hex Hexadecimal Plain-text encoding of a binary file as ASCII hexadecimal digits.
.boo Bootstrap A somewhat more compact plain-text encoding of a binary file (see below)
.com Command Usually a VMS command file or DCL procedure (plain text).
.mss Manuscript Scribe markup language source for documentation, plain text
.ps PostScript Document for printing on a PostScript printer (not plain text)
.uue UUE Uuencoded files: an old Unix plain-text encoding for binary files: "Unix-to-Unix Encoding". Encode: uuencode; Decode: uudecode. Once ubiquitous, now hard to find. On Ubuntu, it can be installed with "sudo apt install sharutils".

Many more extensions can be found, for example for source code (.c, .h, .pas, .pl1, .for, .lsp, etc), but all files (with very few exceptions, such as PDF and PostScript) are plain text, unless they are in the archives or bin directories. More about the Kermit archive after the big table.

Here are the programs in the Kermit software archive. In addition to these, there are hundreds, perhaps thousands, of Kermit protocol implementations in commercial and shareware software packages such as Reflexions, Crosstalk, Procomm, Hyperterminal. Kermit protocol is also embedded in numerous devices, including routers, switches, factory-floor devices, medical devices and implants, cash registers, and perhaps most famously, HP calculators.

C-Kermit: Kermit in C for many operating systems [Website]   [Documentation]  [Binaries] [C-Kermit 10.0 Preview]
C-Kermit is the most portable of all Kermit programs. It is also the basis for Kermit 95, MacKermit, and the forthcoming C-Kermit for Windows.
Unix is an operating system family that comprises Linux, FreeBSD, NetBSD, Mac OS X, HP-UX, AIX, Solaris, SCO, and many others both open and proprietary; current and defunct; C-Kermit is available for all of them: see complete list. There are approximately 700 distinct targets in the C-Kermit makefile for Unix and about 1700 Unix C-Kermit binaries in the archive (names starting with "cku").
VMS, also known as OpenVMS, is a proprietary operating system developed at Digital Equipment Corporation (DEC), which passed to Compaq and then to Hewlett-Packard (HP). C-Kermit is available for VMS versions old and new on VAX, Alpha, and IA64.

The versions above are the big ones in terms of popularity, coverage, scope, or longevity. From here down we go in approximately alphabetical order. Many of these are adaptations of early versions of the Kermit programs listed above to specific platforms. IMPORTANT: C-Kermit is listed for some of the platforms below, showing the version that was last known to build and work there, and where to find binaries for it. This does not necessarily mean that later versions do not work on those platforms, only that there have been no reports either way. Ditto for G-Kermit. Obviously not every single platform is listed for C-Kermit or G-Kermit here because there are thousands of them. Even for modern platforms; click here to see the table for C-Kermit 9.0.

The following, together with PRIME Kermit, were the first to have sliding windows packet transport, needed for long-distance file transfers across TELENET. This is a prototype program; the algorithms were refined later in C-Kermit and MS-DOS Kermit. This work was funded by THE SOURCE, a TELENET-based online service provider using PRIME computers, many of whose clients had PCs.

More about the Kermit software archive

The uncompressed unarchived files are not available via HTTP because HTTP, the protocol of the Web, doesn't have a way to refer to or deal with a group of files, like FTP can do with its MGET command. Therefore we have to bundle the files for each Kermit program into Zip or Tar archive so each Kermit program can be fetched with a single click. The danger is that years from now, Zip and Tar and Gzip will go out of style and nobody will be able to decode these files any more. The FTP column is for FTP access to the individual files in clear text. This is problematic also because (a) you have to download each one individually, and (b) FTP access is increasingly blocked by firewalls. Of course, if FTP is not blocked, you can always use it the old-fashioned way with the advantages that (a) you can use the MGET command with wildcards to specify file groups; and (b) you can specify whether files are to be transferred in text mode or binary mode, a vital distinction that browser-based FTP clients don't allow for. NOTE: The Kermit Project FTP server is Unix-based; therefore text files are in Unix format (lines terminated by linefeed only, not carriage return and linefeed [CRLF]). ZIP archives have text files in CRLF format; tar.gz files have them in Unix format.

I have not made any attempt to include offsite links to information about the many platforms where Kermit programs run, because any links will inevitably go stale and I might not be around to update them. If you want to find out more about some platform, search for it in Google or Wikipedia, or whatever has replaced them by the time you read this.

For the history of each Kermit program, there are several onsite resources:

  1. The Info-Kermit Digest, a public mailing list run by the Kermit Project from 1983 to 1995 over ARPANET, BITNET, CSNET, CCNET, Usenet, LISTSERV, etc, and eventually the Internet.
  2. The Kermit Newsgroups, comp.protocols.kermit.misc and comp.protocols.kermit.announce, which replaced the high-maintenance labor-intensive mailing list in 1994-95, and was active until 2011, maybe beyond. Newsgroup archives are available (as of this writing) in Google Groups here and here. However, there is not much filtering in the Google archive; the real messages are mixed with a fair amount of spam. As of 16 August 2011, the newsgroup archives are also available in the Kermit software archive (table just below).
  3. The program's source files and accompanying documentation, available in the big table above.
Note: the items in the table below were copied from Columbia University to Kermitproject.org on 17 February 2021 because the Columbia links had stopped working even though the material was still there.

Brief history of the Kermit Archive

In the early days of the Kermit Project, there was no network for distributing Kermit programs; therefore we sent them out on 9-track magnetic tape (at our own expense*). At 1600bpi, each 10-inch reel held approximately 50MB of data. Portable tape formats such as ANSI D and IBM SL (as opposed to platform-specific ones like DUMPER, BACKUP, and Tar), had no provision for binary files, so all files had to be text (when making IBM tapes, we either wrote them on the IBM mainframe or we used a utility that we wrote to make IBM EBCDIC OS Standard-Label tapes on Unix (see below).

Also there is no directory structure on these tapes; therefore files had to be grouped by filename. All files for a particular Kermit program had to be named with a unique 2- or 3-character prefix.

Furthermore, some of the most popular platforms in the early 80s, such as TOPS-10 and RT-11, restricted filenames to 6.3 format — six or fewer characters, a period, and then an "extension" of one to three characters. Thus, even for platforms that had more liberal naming rules, we tried to keep names within the 6.3 format so the files could be read, stored, and re-distributed from platforms that tolerated only short names.

Initially all the Kermit programs fit on one tape. But soon with the great flourishing of Kermit programs in the mid-1980s, the distribution grew to four tapes. By this time we also had our primary development and distribution machine, CU20B (Columbia University DECSYSTEM-20 B) on the ARPANET. Thus the Kermit files were split up into four directories:

A Popular microcomputers
B Popular minis and mainframes
C Less popular microcomputers
D Less popular minis and mainframes

It was a neverending struggle to keep each directory within the capacity of a tape reel. Every time a new version of some Kermit program was released, a tape overflowed. Then we would have to look for ways to save space. This was typically done by concatenating all the files for a particular Kermit program into one big (plain-text) file, with markers showing the divisions and filenames. This eliminated large numbers of interfile gaps, each of which took up a disproportionate amount of tape.

It must be said that also we removed some Kermit programs from circulation when they were "superseded" by a "better" version for the same platform. We did this simply because we could not fit a lot of alternative versions for the same platform on one tape.

By the mid-1990s, with the growth of the Internet, tape distribution had diminished to a trickle so we did not have to be so careful about the size of each directory. Meanwhile, the ever-increasing volume of Kermit Digest issues, newsletters, newsgroup archives, version lists, and so on demanded a "tape" of their own, E, while C-Kermit grew to such proportions that it received its own directory too, F (now ckermit). Also, since Kermit binaries and Zip and Tar archives could be distributed over the new networks (Internet, for example, unlike, say BITNET), a directory (archives) was created for them too.

For the assembly of this new Internet archive, all of the superseded programs have been made available again, and all of the text archives have been unpacked into their original constituent files with their original names (but made lowercase, if they were uppercase).

Another noteworthy event is that on August 16, 1988, we moved all the Kermit files from CU20B to a Unix machine (it was either a VAX-11/750 running 4.2BSD, or a VAX 8700 running Ultrix), just before CU20B was turned off for the last time. Since neither Kermit nor FTP nor ANSI-format tapes had a mechanism to preserve file dates, a lot of the older files in the present archive have that date. In putting this archive together, some of the earlier file dates were restored, but not consistently.

* In 1985 or thereabouts, we were spending so much programmer time making and shipping tapes that we were told to start charging for them. And thus the "Kermit business" was born, with a production staff, business manager, and a machine-room/factory.

BOO Files

In the early 1980s, to transfer binary files (e.g. over BITNET) or send them by email, a plain-text encoding was usually needed. The most obvious binary-to-text transformation is to represent every 8-bit byte by two hexadecimal characters. But this makes the file twice as long, and in those days typical communication speeds were 300 to 1200 bits per second. So we came up with something called a BOO file, short for bootstrap*. The idea being that if you could get this file onto your PC somehow, then you could "type in" or download a simple program to turn it back into the original binary file. The encoding is similar to Base64 or UUENCODE, but adds a rudimentary form of compression. A BOO file contains only 7-bit ASCII printable characters (with lines separated by CR or CRLF, depending on the platform). Here's the first bit of a typical BOO file:


The first line gives the name of the original binary file, and the remaining lines are its encoded contents. Tildes (~) indicate places where compression was done. The writing of BOO-file encoders and decoders became quite the cottage industry. You can read the specification here, and you can find an impressive collection of BOO-file makers and decoders in the table below. In any case, with this mechanism we were able to mix text and "binary" files in the same directory and put them on tape. Although BOO files never caught on to any great extent in the wider world, they did their job for Kermit. In retrospect, a big improvement would have been a mechanism for gathering multiple files into a single BOO file.

* "Bootstrap" refers to lifting up oneself by one's own bootstraps (a parodox). In Kermit jargon, it refers to a way of getting a file-transfer program onto a computer that does not have one, which itself is a paradox if you think about it. A textual encoding (BOO or Hex, for example) would be displayed on the microcomputer's screen (conceptually) with the display copied or "captured" to disk. Then the captured lines of text would be decoded into the original executable program. But suppose the microcomputer did not have even a terminal emulator? You can see the lengths to which we would go in those days to "bootstrap" Kermit onto new computers in the CP/M Kermit User Guide, pp.20-23.

The Kermit Protocol

The Kermit protocol as of 1986 is defined in the book Kermit: A File Transfer Protocol, Digital Press (1987), which is out of print but can still be ordered on Amazon (click the link) and, as of 2016, can be viewed online. The same definition, more or less, appears in the 1986 (and final) edition of the Kermit Protocol Manual. Since then, a lot of new features have been added (see overview and timeline) but often not documented anywhere except in notes that were never published before. Here they are:

The protocol manual is quite serviceable; it covers file attributes as well as both long packets and sliding windows, so it can be the basis of an efficient and fairly advanced Kermit implementation. It does not, however, cover character-set conversion, Unicode, "resend" (recovery of interrupted binary-mode transfers), streaming, control-character unprefixing, cross-platform directory-tree transfer, or various client-server protocol extensions. The files in this section are mostly plain text, but there are some typeset files too:

The KERMIT Acronym

In 1982 or 83, as we saw Kermit protocol and software leaking out of Columbia University and spreading all over planet, Bill Catchings (one of the original Kermit developers) became slightly concerned about trademark infringement so one day he tried to put together a series of words that KERMIT might stand for. It was really more of a joke than anything:

KL10 Error-free Reciprocal Micro-Interface Transfer

(and some similar variations). KL10 was the processor of our DECSYSTEM-20 where the first Kermit program was written. Of course the protocol was designed to work on any computer but Bill couldn't find anything appropriate that started with K. Anyway, this legend was put into one or two pieces of source souce, which escaped from Columbia, and then found their way into other pieces of source code that you will find in this archive, and still provokes a great deal mirth. For our part, we removed it from our own code as soon as had a letter of permission from Henson Associates to keep using the name Kermit.

Patterns and Trends

Kermit programs fall into roughly two categories: one-shot minimalist versions, and long-lived and continuously elaborated ones. You can tell the difference pretty much by the version number and the latest release date. Any version number greater than 1 is a Kermit program that received a fair amount of attention; the higher the number, the more attention (in general). That's not to say that every 1.x version is crude; one counterexample is G-Kermit 1.00, which I wrote with the specific intention of never having to touch it again. Another is Macintosh Kermit, which never quite reached 1.0 level but was widely used.

As to languages, at first we had a great proliferation of them, including many different assembly languages (PDP-10, IBM mainframe, 8080, 8086, mc68000...) But by, say, the mid-90s, the only non-interpretive language that mattered any more was C and its offshoots. Which is kind of a shame because many of the older languages were more consistent, expressive, powerful, stable, and robust. And better documented and less aggravating.

Unix versions covered by C-Kermit and/or G-Kermit

This list belongs in the main table but it's too big. If a name appears on this list, it means that C-Kermit or G-Kermit is available for that machine/operating-system combination, or it was at some point. If a name doesn't appear, that does not mean that C-Kermit and/or G-Kermit can not be built for it. In the case of C-Kermit, an older release might be required, as is definitely the case for 16-bit Unix versions such as XENIX, 2.xBSD, etc. Support for old systems has never been removed from C-Kermit source code or the makefile, but that support might not have been tested in many years, since the last time anybody involved in Kermit development had access to that platform.
