管理 GSM 调制解调器响应

Question

---

I'm creating a small program in Visual Basic, using Visual Studio 2010, which communicates with a GSM modem via serial port. The connection works, I can even communicate properly with the modem and I can also send sms and mms.. But I can not handle the modem answers... I'll explain: If I send a command like AT + CSQ modem replies with + CSQ 22.0. This command gives me the value of the signal as a response on a scale of 0-30... I can see on the screen (in a dedicated console) but I would like to manage the response in the sense that I would do something like that

IF (answer.text = "+CSQ 22,0") Then 
      label1.text = "Good"
ELSE
       label1.text = "Bad"
END IF

Is it possible?

Try using SerialPort ReadLine method to get the response to the command you send.
