Its very easy. The command used to send sms is AT+CMGS="phone no" and before that you have to send AT+CMGF=1 to select text mode. After each at commands you have to add \r\n to jump to the next line. If you send AT+CMGS then you can send the message. After that send hex value for CTRL+Z which is 0AH i think. Before this you have to configure serial port properly.
