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.

Unfortunatly to me Joe's code seems to be much larger than the minimum
needed and dificult to understand.
Port is simply the handle to the COM-DRV++ comport functions.
I looking at my code snippet you cannot tell what "Port" is then you
dont need to answer.
The snippet is only the thread that checks if char came in serial
port.
