Varias portas serie (tx/rx)

-

boas amigos,

estou hoje começar minha aventura no mundo arduino ( embora ja tenha um ard. mini pro muito tempo).
desenrasco-me bem com pics (linguagem pic basic pro)bem mas vamos ao que interessa mesmo, eu gostaria que alguém me pudesse mostrar um simples código onde eu posso receber e enviar informação serie entre 2 dispositivos e depois enviar mesma para o serial monitor ide arduino, basta mesmo uma coisa muito simples para eu ficar com ideia e depois desenvolver.

muito obg pela vossa ajuda que é muito preciosa para que se esta iniciar :)

bom vc quer usar realmente rs232 ou apenas "simular" uma comunicação serial entre dois arduinos?
para começar, e entender leia referência ao softwareserial library http://www.arduino.cc/en/reference/softwareserial, ele permite comunicação serial através dos outros 10 pinos arduino duemilanove.
no softwareserial library tem um exemplo simples, de como funciona.
