If you use Windows

HANDLE m_hParallelComm = CreateFile(portName,GENERIC_READ | GENERIC_WRITE, 0, NULL, OPEN_EXISTING, 0,NULL); 

if(m_hParallelComm == INVALID_HANDLE_VALUE)
    return false;

ReadFile( m_hParallelComm,data,  dwSize, &dwNumberOfBytesToRead, NULL);
CloseHandle(m_hParallelComm);

For read file function refer this
