I am getting the impression that only "Master" side of these protocols are in scope. Or?
In any case, I have previously made a C library for ModBus (from spec), and I could see if it is worth dusting off and contribute. Is it of interest, or? It might not be complete, and I recall it follows a OO-style of C programming that not everyone appreciate.
