我自己编了一个VC小程序，里面用了DBGrid和RomoteData，MSComm控件。
编译时都没错，但是运行时出现如下错误：
Debug Assertion Failed!

File: objcore.cpp
Line:43Fir information on how your program can cause an assertion failure, see the Visual C++

原代码如下：
/设置串口
void CSerialComnView::OnButton2()
{
// TODO: Add your control notification handler code here
CSetPortDlg myport;
myport.m_strSettings=_T("9600,n,8,1");
m_mscomm.SetSettings(myport.m_strSettings);
m_mscomm.SetCommPort(1);
if (m_mscomm.GetPortOpen())
AfxMessageBox("Port is already open!");
