Algún url que me > pueda sugerir para documentarme? El C55 viene con un cable que se puede conectar por un 9-pin conector a una PC o laptop si esta tiene un puerto para tal. En cuanto a los AT comandos te adjunto un resúmen de un test que hice con un celular Bosch 908 (que funciona en este sentido como el C55). Es inglés, lo siento.
