send sms by GSM modem

###Introduce

• The origin model is from http://bbs.chinaunix.net/thread-1793815-1-1.html

• Send SMS is ok, recv and delete need to check.

• Have been test for Fedora 20, Ubuntu 12.04

###How to use

1. Build

   • Make

2. Check device

   • Plug a GSM modem to your machine with USB line The device I used is wavecom gsm m1306b, and its interface is usb.
   • Use command lsusb to check, mostly it will show as "...PL2303 Serial Port"
     [dennis@localhost sms]$ lsusb

3. Usage, should run the application with root authentication

   • ./sms [device_name] [phone_number] [sms_text]

4. Sample, test on Fedora 20. Because my device antenna is broken, so most of the time failed to send message.
