- PacketSetReadTimeout: instead of calling with a very short timeout,
  now we call it with -1 which means no timeout.
- Psyon found that Peter Tattam's changes, while necessary for win95, broke
  WinNT/2000.  So now on Windows NT/2000, we still call
  WaitForSingleObject(lpAdapter->ReadEvent,0) but we ignore the return value.
