C++如何接受串口返回的数据

Question

void CNewTestDlg::OnStart()
{
// 55 55 00 00 00 00 00 00 00 00 00 00 00 00 00 00 FF 03 FD D4 14 01 17 00
CByteArray SendTemp,hexdata;
COleSafeArray safearray_inp;
CString strtemp;
SendTemp.SetSize(24);
SendTemp.SetAt(0,0x55);
SendTemp.SetAt(1,0x55);
SendTemp.SetAt(2,0x00);
SendTemp.SetAt(3,0x00);
SendTemp.SetAt(4,0x00);
SendTemp.SetAt(5,0x00);
SendTemp.SetAt(6,0x00);
SendTemp.SetAt(7,0x00);
SendTemp.SetAt(8,0x00);
SendTemp.SetAt(9,0x00);
SendTemp.SetAt(10,0x00);
SendTemp.SetAt(11,0x00);
SendTemp.SetAt(12,0x00);
SendTemp.SetAt(13,0x00);
SendTemp.SetAt(14,0x00);
SendTemp.SetAt(15,0x00);
SendTemp.SetAt(16,0xFF);
SendTemp.SetAt(17,0x03);
SendTemp.SetAt(18,0xFD);
SendTemp.SetAt(19,0xD4);
SendTemp.SetAt(20,0x14);
SendTemp.SetAt(21,0x01);
SendTemp.SetAt(22,0x17);
SendTemp.SetAt(23,0x00);
m_ctrlComm.SetOutput(COleVariant(SendTemp));
}

然后怎么写才能接收串口返回的数据？本人小白，谢谢各位大神了
