CSerial

http://www.codeproject.com/system/serial.asp

GPL Licence 로 나름대로 사용하기도 좋고 나온지 오래되었으니 +_+ 꽤 실용성있고 제일 맘에 드는건 유니 코드를 제대로 지원해주시는 센스가 있어서 -_-;

1. CRichEditCtrl 을 Override하시는 클래스를 하나 생성해주시곤 CSerial* pSerial 하나 생성 WM_CHAR에 다음과 같은 소스를 추가
[code]
void CRichCommEdit::OnChar(UINT nChar, UINT nRepCnt, UINT nFlags)
{
    if (m_pSerial && m_pSerial->IsOpen())
    {
        char ch = static_cast<char>(nChar);
        m_pSerial->Write(&ch,1);                // command write
    }

    if (m_bEcho)
    {
        CRichEditCtrl::OnChar(nChar, nRepCnt, nFlags);
    }
}
[/code]
2. CSerialMFC m_serial 멤버 변수 할당, CRichEditCtrl Override한 클래스를 가지고 멤버 변수 할당.
3. Init 부분에 아래와 같은 코드 입력
[code]
    if (m_serial.Open(L"\\\\.\\COM20", this) != ERROR_SUCCESS)
    {
        AfxMessageBox(_T("Unable to open COM-port"),MB_ICONSTOP|MB_OK);
        GetParent()->PostMessage(WM_CLOSE);
        return 0;
    }

    // Setup the COM port
    if (m_serial.Setup(CSerial::EBaud115200,CSerial::EData8,CSerial::EParNone,CSerial::EStop1))
        return false;

    // Setup handshaking
    if (m_serial.SetupHandshaking(CSerial::EHandshakeHardware))
        return false;

    VERIFY(m_rich.Create(WS_VISIBLE|WS_CHILD|WS_BORDER|ES_AUTOHSCROLL|ES_AUTOVSCROLL|ES_LEFT|ES_MULTILINE,
        CRect(0,0,640,480),this,0));

    m_rich.m_pSerial = &m_serial;
[/code]
ex > COM포트가 4를 넘으면 가상으로다가 해야기 땜시로 \\\\.\\를 붙여주도록 해야합니다잉
    > 다이얼로그라 강제로 사이즈를 640, 480을 주었지만 실제적으로는 WM_SIZE에서 재조정해주면 됩니다요 물론 현재 윈도우 사이즈 가져와도 되고

4. 요거 PASTE 선언은 protected로 다가 해주면 되3
