与超级终端通信[QT和WINApi]

Question

我写程序与调制解调器（它使用海耶斯命令）通信，这是行得通的。 GUI是用QT编程的，但是与COM端口的通信是用winapi库编写的。当我想将我的程序消息从一台计算机发送到另一台计算机时，我遇到了问题，我无法发送波兰字符（它们被'？'重新填满），我该如何解决它？有没有人有想法？而且我还有一个问题，我无法从我的程序发送消息给Microsoft HyperTerminal，HyperTerminal收到了一些东西，但不是我发送的内容。 THX对于任何帮助:)

重要的部分代码： 与连接端口：

portHandle = CreateFile (portName, GENERIC_WRITE | GENERIC_READ, 0, NULL, OPEN_EXISTING, 0, NULL); 

GetCommState (portHandle, &dcb); 
switch(ui->comboBox->currentIndex()) 
{ 
     case 0 : dcb.BaudRate=CBR_110; break; 
     case 1 : dcb.BaudRate=CBR_300; break; 
     case 2 : dcb.BaudRate=CBR_600; break; 
     case 3 : dcb.BaudRate=CBR_1200; break; 
     case 4 : dcb.BaudRate=CBR_2400; break; 
     case 5 : dcb.BaudRate=CBR_4800; break; 
     case 6 : dcb.BaudRate=CBR_9600; break; 
     case 7 : dcb.BaudRate=CBR_14400; break; 
     case 8 : dcb.BaudRate=CBR_19200; break; 
     case 9 : dcb.BaudRate=CBR_38400; break; 
     case 10 : dcb.BaudRate=CBR_56000; break; 
     case 11 : dcb.BaudRate=CBR_57600; break; 
     case 12 : dcb.BaudRate=CBR_115200; break; 
     case 13 : dcb.BaudRate=CBR_128000; break; 
     case 14 : dcb.BaudRate=CBR_256000; break; 
} 

dcb.fBinary = TRUE; 
dcb.fParity = TRUE; 
dcb.fOutxCtsFlow = FALSE; 
dcb.fOutxDsrFlow = FALSE; 
dcb.fDtrControl = DTR_CONTROL_ENABLE; 
dcb.fDsrSensitivity = FALSE; 
dcb.fTXContinueOnXoff = TRUE; 
dcb.fOutX = FALSE; 
dcb.fInX = FALSE; 
dcb.fErrorChar = FALSE; 
dcb.fNull = FALSE; 
dcb.fRtsControl = RTS_CONTROL_ENABLE; 
dcb.fAbortOnError = FALSE; 
//dcb.ByteSize = dataBits; 
dcb.DCBlength = sizeof (DCB); 

switch(ui->comboBox_3->currentIndex()) 
{ 
    case 1 : dcb.Parity = EVENPARITY; break; 
    case 3 : dcb.Parity = MARKPARITY; break; 
    case 2 : dcb.Parity = ODDPARITY; break; 
    case 4 : dcb.Parity = SPACEPARITY; break; 
    case 0 : dcb.Parity = NOPARITY; break; 
} 

switch (ui->comboBox_4->currentIndex()) 
{ 
    case 0 : dcb.StopBits = ONESTOPBIT; break; 
    case 1 : dcb.StopBits = ONE5STOPBITS;break; 
    case 2 : dcb.StopBits = TWOSTOPBITS; break; 
} 

switch (ui->comboBox_2->currentIndex()) 
{ 
    case 0 : dcb.ByteSize = 5; break; 
    case 1 : dcb.ByteSize = 6;break; 
    case 2 : dcb.ByteSize= 7; break; 
    case 3 : dcb.ByteSize = 8; break; 
} 

SetCommState (portHandle, &dcb); 

GetCommTimeouts (portHandle, &CommTimeouts); 
CommTimeouts.ReadIntervalTimeout = MAXDWORD; 
CommTimeouts.ReadTotalTimeoutMultiplier = 0; 
CommTimeouts.ReadTotalTimeoutConstant = 0; 
CommTimeouts.WriteTotalTimeoutMultiplier = 10; 
CommTimeouts.WriteTotalTimeoutConstant = 1000; 
SetCommTimeouts (portHandle, &CommTimeouts); 

发送味精：

void MainWindow::Send(char c) 
{ 
    do 
     {WriteFile(portHandle, &c, 1, &cbWritten, NULL); 
     } 
    while (!(cbWritten)); 
} 

void MainWindow::on_pushButton_clicked() 
{ 
    QString str = ui->lineEdit->text(); 
    std::string str2; 
    ui->lineEdit->clear(); 
    str2 = str.toStdString(); 
    for(int i=0; i < str2.size();i++) 
    { 
     Send(str2[i]); 
     //qDebug()<< str2[i]; 
    } 
    Send(char(13)); 

} 

接收味精：

void ReaderThread::run() 
{ 

    char c; 
    while(1) 
    { 

     c = Receive(); 
     if(c==13) 
     { 
      emit insertPlainText("\n"); 
     } 
     else 
     { 
      emit insertPlainText(QString(c)); 

     } 

    } 
} 

char ReaderThread::Receive() 
{ 
    char c; 
    do{ 
     ReadFile(portHandle, &c, 1, &cbRead, NULL); 
    } 
    while (!(cbRead)); 
    return c; 

}

你是将16位QChar打入8位钻孔。您需要为每个字符发送和接收2个字节，或将自己限制为8位字符编码。
