推荐答案

如果它被Windows用作调制解调器认可则所需的驱动程序会自动呈现它作为一个串口，就像任何其他调制解调器和放大器;你可以使用它的端口名称和放它交流; System.IO.Ports.SerialPort 。如果你想访问AT / GSM指令集有像 GSMComm 库。

If its recognised by windows as a modem then the required drivers should automatically present it as a serial port, just like any other modem & you can communicate with it using its port name & System.IO.Ports.SerialPort. If you want to access the AT/GSM command set there are libraries like GSMComm.
