With help from ChatGPT and Gemini, and more reliable help from users on this list, I've put together something that shows how MLLP can be received and sent with and without SSL, and how a simple dashboard and yaml route loader can be implemented.
It's at https://github.com/mjtrac/mc.git and I've apologized there for my lack of knowledge and presumed lack of use of best practices. Any and all suggestions are welcome and encouraged. Thanks, especially to those who've answered my questions here. Mitch
