Arduino to Arduino communication


Im working in a simple server of communications between a arduino to another arduino, via serial, i've tried to use i2c, and its good, but now i need serial, i have a mega and 2 arduinos, and i want to use the 3 serial ports avaiable from the mega... i've made some examples, but im not able to put them to work nicely... is there some library or anyone has some squeleton pde for making 4 arduinos communicating good and nice??



making 4 arduinos communicating good

That's a bit vague. There is always the DMX protocol based on RS482. That is a master slave arrangement.
