就是紅色這段呼叫，干什么的，對cmdGetPalam這個集做了什么操作？
void CComToKeyBoardDlg::OnBnClickedButton8()
{
// TODO: 在此添加控制元件通知處理程式代碼
char cmdGetPalam[20] = {0x01,0x04,0x00,0x00,0x00,0x10,0xB0,0x13};
CString str;
//int temp;
unsigned short crcResult;
if(bFlagComm)
{
GetDlgItem(IDC_EDIT2)->GetWindowTextA(str);
Address = _ttoi(str);
cmdGetPalam[0] = Address;
RcvIdentCode = 0x81;
crcResult = MBCRC16((unsigned char*)cmdGetPalam,6);
cmdGetPalam[6] = crcResult;
cmdGetPalam[7] = crcResult>>8;
m_ComPort[0].WriteToPort(cmdGetPalam,8);
WaitForSingleObject(m_handle,200);
m_ComPort[0].WriteToPort(cmdGetPalam,8);
WaitForSingleObject(m_handle,200);
m_ComPort[0].WriteToPort(cmdGetPalam,8);

bFlagCollecting = true;
}
else
{
MessageBox("串口沒有打開!");
