I’ve ran into a dilemma with a project. I need to get several serial links between 2 locations, but only have access to 1 serial channel. I already have an arduino mega at each end. Does anyone know of a library or setup that can ‘tunnel’ a couple of low baud serial connection over a higher baud setup?
I thought I would ask before I started attacking it. I can see how it could be done, but can also see a lot of pitfalls, does anyone know of an existing library that can do this?
