RE: Serial worker thread help

I have a serial worker thread that works with COM-DRV++(serial
wrapper) below.
This worked fine until I needed it to work under Vista.
I have switched to the CreateFile(), ReadFile(), WriteFile() methods.

UINT SerialThread( LPVOID Param ) //Thread to monitor serial activity
{
  HWND hDlg = (HWND)Param;
  int DataByte=0x00;
  int Count=0;
  int i;

  while(TRUE){
    Count=0;
    while(Count == 0){
      Count = Port.BytesInReceiveBuffer();
      Sleep(50);
    }
    DataByte=Port.GetByte(18);
    if (DataByte == 0x10){
      for (i=0; i<33; i++){
        DataByte=Port.GetByte(18);
        Bar[i]=(DataByte & 0xff);
      }
    }
    ::PostMessage(hDlg, MY_SERIAL, (WPARAM)0, (LPARAM)0);
  }
  return TRUE;
}

When the char 10h is received it then gets 33 more chars (all 8bit).
I need to know how to change this to the ReadFile() method.

Thanks
