About C-Kermit

C-Kermit is a communications program from the Kermit Project, which has been developing Kermit software since 1981. It makes serial and network connections, acts as a terminal and transfers files, and its built-in scripting language can automate sessions and transfers.

The project is open source and still maintained by Frank da Cruz. C-Kermit 10.0 was in beta testing as of March 2025, and a separate Windows program, Kermit 95, is also in beta.

Strengths

  • Handles serial lines as well as network connections
  • Built-in scripting language for automated sessions
  • Long history and extensive documentation

Limitations

  • The current 10.0 release is still in beta
  • Command-line interface with a steep learning curve
