Can you send something else like text. I ask because it matters if you are able to send something or nothing at all.

Sounds like you might want to read the documentation for your LoRA module to understand how it actually works and what it expects.

I suspect that you need to look at how it ''escapes'' special characters, like you do in C '\n' or ESC ESC for other protocols.
