how to use GSM with arduino?

Hi, I'm newby and I'd like to connect arduino with a GSM device. I bought GSM SIEMENS TC35 SMS Module Board RS232 UART Serial Arduino + Voice adapter http://www.ebay.com/itm/GSM-SIEMENS-TC35-SMS-Module-Board-RS232-UART-Serial-Arduino-Voice-adapter-/270851051007?pt=LH_DefaultDomain_0&hash=item3f0ffb0dff#ht_3985wt_954

Now... how can I connect it to arduino? where can I find a tutorial to do that? how can I send an sms text?

Thank you in advance, Andrea

From the name it would probably be connected to +5 (power), Ground, RX, and TX. If you want to use the USB cable to communicate with a PC you should try SoftwareSerial to use two data pins for serial communication with the GSM board.

To figure out how to use it you should look for a manual for the SIEMENS TC35 GSM module.
