In fact, this reminds me a bit of Discworld where they did have something kinda-similar, only they used line-of-sight signalling towers that were mechanical in nature that they called the Clacks (which I assumed was from the sound of the towers' moving parts). They didn't go full on Morsepunk, but Pratchett did run with the idea in a few different directions.
