I explored that recently. Here is how I quickly tested them: Connected (tx+rx) to (rx+tx) then sent messages between them. The test was < 10 lines of code.

I don't remember exactly but I think those 3 use a UART and one is connected to USB. I also don't remember if there are serial libraries for software serial which would increase the number of serial, maybe.

That is pretty vague sounding, sorry.
