Care arata cam asa? Tu la ce tensiune l-ai alimentat din exterior?Pot folosi aceeasi schema pentru a conecta telefonul la un microcontroler pic? Daca da, este nevoie de mai mult de un divizor de tensiune pe linia tx ce duce la pic? Mai este necesoar max232-ul sau pot folosi alta schema mai simpla?

Am realizat schema, si am alimentat montajul la 9V. Am citit tensiunea pe portul serial ce duce la PC, si era de 8,4V. Este deajuns, sau e nevoie de o tensiune mai mare pt a realiza comunicarea seriala? Baud Rate-ul la care trimit datele este detectat automat de t610? Am incercat sa trimit comenzi AT, dar ce se vede in imagine am primit. Care ar putea fi problema?
