a trouble problem about CMSCOMM.OCX

[Grrrr]

:confused::confused::confused: while i try to use atciveX control CMSCOMM.ocx with VC++6.0, i find some trouble problem. 1. must to use 'a &= 0x7F;' because that the code received have a wrong format,but it's right after i use 'a &= 0x7F;'... 2. some code can't be received sometimes. such as: 'thanks', only can receive 'anks' the code as below: void CMainFrame::OnOnCommMscomm() { VARIANT vat_input; COleSafeArray oleSA_input; LONG length, i; BYTE data[1024] = {0}; CString msg; char a = 0; INT nEvent = m_Comm.GetCommEvent(); if (nEvent == 2 ) //|| nEvent == 3 || nEvent == 6) { oleSA_input.Clear(); memset(&vat_input, 0, sizeof(VARIANT)); vat_input = m_Comm.GetInput(); m_Comm.SetInBufferCount(0); oleSA_input = vat_input; length = oleSA_input.GetOneDimSize(); for (i=0; iGetActiveDocument()); if (pDocu->m_CurrentStatus == STATUS_START) { pDocu->DoAnalyseData((LPTSTR)(LPCTSTR)m_strINComstring); } m_strINComstring.Empty(); } else if (nEvent>1000) { if (m_Comm.GetPortOpen()) { m_Comm.SetPortOpen(FALSE); } m_Comm.SetPortOpen(TRUE); } } and the setting as below: m_Comm.SetCommPort(pComSet->ComPort); m_Comm.SetInBufferSize(4096); m_Comm.SetInputMode(1); m_Comm.SetInputLen(0); m_Comm.SetOutBufferSize(4096); m_Comm.SetRThreshold(1); m_Comm.SetSThreshold(0); m_Comm.SetEOFEnable(TRUE); m_Comm.SetDTREnable(TRUE); m_Comm.SetHandshaking(0); m_Comm.SetNullDiscard(FALSE); m_Comm.SetRTSEnable(FALSE); m_Comm.SetSettings(_T("115200, n, 8, 1")); who can helpp me!! thanks!!! :confused::confused:
