help sim900 sms (resolvido)

Olá pessoal,

chegou essa semana um shild que comprei da china (http://dx.com/p/freaduino-gsm-gprs-shield-expansion-board-for-ardui...)

É um SIM900.

Mas estou apanhando para enviar um sms via software.

Conectei e via telnet consegui enviar o sms,  mas programando e salvando nada...

usei esse que achei na net.

Obrigado pessoal

#include <NewSoftSerial.h>

NewSoftSerial mySerial(2, 3);

void setup()
{

delay(10000);

Serial.begin(19200); //Default serial port setting for the GPRS modem is 19200bps 8-N-1
Serial.print("\r");
delay(1000); //Wait for a second while the modem sends an "OK"
Serial.print("AT+CMGF=1\r"); //Because we want to send the SMS in text mode
delay(1000);

Serial.print("AT+CMGS=\"981510000\"\r"); //Start accepting the text for the message
//to be sent to the number specified.
//Replace this number with the target mobile number.
delay(1000);
Serial.print("SIM900 and Arduino say Hi!\r"); //The text for the message
delay(1000);
Serial.print(0x1A,BYTE);
Serial.print(26,BYTE); //Equivalent to sending Ctrl+Z

}

void loop()
{
//We just want to send the SMS only once, so there is nothing in this loop.
//If we put the code for SMS here, it will be sent again and again and cost us a lot.
}
