I am trying to write a buffer in lpBuf.
But whenever the buffer has a single NULL character,
The line at WaitForSingleObject(osWrite.hEvent, INFINITE);
waits forever and I cannot go further.

How do I sucessfully send NULL characters.


code snipette.......


  if (!WriteFile(hComm, lpBuf, dwToWrite, &dwWritten, &osWrite))
  {
     if (GetLastError() != ERROR_IO_PENDING)
     {
        // WriteFile failed, but isn't delayed. Report error and abort.
        fRes = FALSE;
     }
     else
     {
        // Write is pending.
        dwRes = WaitForSingleObject(osWrite.hEvent, INFINITE);
