Software Notes

This document provides some notes on the open source release of Kermit 95 (now called C-Kermit for Windows) and some of my plans for it. The latest release is up on the Kermit Project website, and the latest source code is available on github. You contact myself (David Goodwin) and Frank da Cruz by emailing

C-Kermit for Windows 10.0 BETA 3 is now available from The Kermit Project Website. This adds SSH, SSL/TLS, and PTY support for Windows XP Service Pack 3 and newer. A feature-reduced build is also available for older Windows systems going all the way back to Windows NT 3.50.

The latest code is, as before, available from github which now has CI setup providing automated builds of the latest code whenever anything changes. The occasional new test build may still appear in when notable changes occur but this will be uncommon and likely only while preparing for a new release which will be made available on the kermit project website.

At the moment my goals are: Fix the stuff thats broken or missing since Kermit 95 and generally get it working nicely on modern Windows (I want to use it instead of PuTTY), while also maintaining and even extending support for vintage windows systems (I want to use it instead of HyperTerm). From the second beta support for modern and vintage windows are provided via three separate builds - a secure one with new features for modern windows, and a feature-reduced insecure one built with a vintage compiler for vintage windows, and an extra feature reduced build specially for Windows NT 3.50 which demands an ancient compiler. Plan is to have a final stable release done by mid-November if possible.

New in Beta 3

Beta 3, released 15 September 2022, is quite a substantial update bringing many improvements. See What's New in Beta 3 for a nice tidy list, or the old unordered list that used to be here.

Plans for the Fourth Beta

Subject to change based on available free time and what I feel like working on. Target is to release this around 17 October. Stuff that is done and guaranteed to go out at the top above the line.


Progress to the fourth windows beta. In New Zealand time (UTC+13)

Ideas for future releases

Coming later to some other C-Kermit for Windows Beta as free time allows - in approximate order of (my) priority:

Those last few port-to-other-CPUs ones are pretty unlikely to happen due to difficulty obtaining (legal) copies of the required compilers. Alpha may happen though - looks like the NT 3.50 SDK includes the required compiler though it would be a pretty feature-reduced version due to the Windows API level supported by Visual C++ 2.0.

Unlikely Activity

Stuff I'd like to see happen but I'm unlikely to do myself - not enough free time, too much other stuff to do

Not Happening

This stuff is not possible and so will not happen

Old Stuff

New in the Second Beta

3rd-party libraries

Kermit95 relies on several obsolete third-party libraries which are behind the various disabled features in C-Kermit for Windows. The specific versions were:
