Title: 6254EU can not read the data
memset(m_pDeviceStatus, 0, 128);
//cout << "m_pDeviceStatus: " << (int)m_pDeviceStatus[0] << endl;
WORD state=dsoHTGetState(m_nDeviceIndex, m_pDeviceStatus);
//cout << "m_pDeviceStatus: " << (int)m_pDeviceStatus[0] << endl;
//cout << "dsoHTGetState: " << state << endl;

if (!(m_pDeviceStatus[0] & 2))
//if (!(state & 2))
{ cout << "数据不可读取" << endl;
return false;
}
cout << "数据可读取" << endl;

this is the code，the value of m_pDeviceStatus[0] =56，so m_pDeviceStatus[0] & 2 is zero，how does it happen，and how can i read data.

the code is from VCDEMO
