问题
I have a USB dongle connected to my laptop which is used to get the internet connection. No need to say it has a sim card and it is possible to send/receive SMS as well. I want to know how can I get the SMS and send SMS using my own C++ windows program, through this SIM card. Is there a way to access the SIM card and do these? Any libraries? I haven't done any USB programming anyway. Please help!
Edit
I just found it is possible with something called "AT Commands" - How to Auto send SMS via Broadband USB dongle?
But the link in the answer is dead. Even though it is AT Command, which lib should I install in order to use it? Please help!

At (Attention) commands can be used to interact with the USB dongle. Each manufacturer has their own At-commands, so you will have to find out one which suits your model (mine was Huawei e173-u). Some of the common ones can be found in the Hayes command set :

Introduction to At commands
You will need to find out which COM port your dongle uses from the Device Manager, then use a serial-port terminal like Putty to test out whether the commands are supported by your dongle. As the libraries developed for sending SMS's are mostly for .Net, you may need to use an SMS gateway instead.
