Someone here was talking about sending / receiving SMS messages. My motive to figure out how to do this on my Neo was that I needed to activate an online account and add more minutes. They wanted to send me an SMS message with my initial password. Necessity being the mother of learning...
I had trouble getting this to work and getting all the text returned using libgsmd-tool. It seems gsmd doesn't care for "unsolicited messages" and when I ask to retrieve all my messages, a lot of data is returned which gsmd doesn't like, and therefore drops it instead of sending it back to libgsmd-tool. That's ok. cu is pretty easy to use - I just used it instead. To get into an SMS mode (there are two modes - PDU and text mode). I think gsmd prefers PDU mode, but I learned to do it text mode. Switching over is easy. You can read up on it here: http://www.developershome.com/sms/operatingMode.asp I think the following will turn off, then on, the gsm modem. I do it in an attempt to reset the modem and start from a known state. If anyone knows anything about this, please elaborate. Turn gsm off: echo 0 > /sys/bus/platform/devices/gta01-pm-gsm.0/power_on Turn gsm back on: echo 1 > /sys/bus/platform/devices/gta01-pm-gsm.0/power_on And fire up cu: cu -l /dev/ttySAC0 Once you get the "Connected." line hit [Enter] a few times or "AT" followed by [ENTER] and you should get an "OK". Now go at it... Turn on echoing so you can see what you're doing (use control-H to backspace on mistakes): ATE1 Then register or "turn on" the network. Can't remember exactly what these commands mean: AT+CFUN=1 AT+COPS Then go into SMS mode: AT+CMGF=1 Now you can play. If you've already sent yourself an SMS message to your phone, you can now retrieve it - and all the others with: AT+CMGL="ALL" +CMGL: 1,"REC READ","907",,"07/07/30,18:21:45-20",129,156 Welcome to T-Mobile!

Your new balance is 140 minutes and the new expiration date is 10-31-2007. Thanks for refilling! OK And to send a message, it's: AT+CMGS="Phone #" Then press the [Enter] key and you'll get a ">" prompt. Enter your message and press control-Z. For example: AT+CMGS="1234567890" > HOWDY Then hit control-Z You should get an "OK" and the message should be on its way. I'm sure someone here can go through and make these directions a little better. Just wanted to get things started - then maybe we can get them added to the wiki. Again - you can learn a lot more about SMS at the above web page.
