今天来使用上一次gprs AT命令来上网做一个实例
同样用的是qben M23的gprs模块
这是在上次界面改进的，只是界面没有美观优化（界面是用QCreate绘制的）
同样gprs模块是通过串口通信的，首先设置串口
下面实现代码
首先是main.cpp文件
#include
#include
int main( int argc, char **argv )
{
QApplication App( argc, argv );
GprsClient Gprs;
Gprs.show();
return App.exec();
}
下面是gprsclient.h文件
#ifndef GPRSCLIENT_H
#define GPRSCLIENT_H
#include
#include
#include
#include
#include
#include
#include
namespace Ui {
class GprsClient;
}

void SetSerialPort();
void SetBaudRate();
void SetDataBit();
void SetStopBit();
void SetCheckOut();
bool setSerial(int fd,int BaudRate, int DataBit, int CheckOut, int StopBit);
bool OpenPort();
int SetConnectGprs(char buf_ip[]);
private slots:
virtual void ChangeSerialPort();
virtual void ChangeBaudRate();

int SerialPort;
int DataBit;
int BaudRate;
int StopBit;
int CheckOut;
int SerialFd;
bool OpenFlag;
};
#endif // GPRSCLIENT_H
下面是gprsclient.cpp

下面是工程文件GprsClient.pro
HEADERS += \
gprsclient.h
SOURCES += \
gprsclient.cpp \
main.cpp
FORMS += \
gprsclient.ui
用QCreate制作一个gprsclient.ui的界面文件（qt4平台）
把上述文件放到Liunx下的一个目录下设置好qt4的平台，再执行qmake，make就ok运行了
具体说明可以看下上期文档和这里代码注释
