TcomPort kann Com11 nicht öffnen

[baumina]

Ja, so stehts im Quelltext auch drin.

Delphi-Quellcode:

// create handle to serial port
procedure TCustomComPort.CreateHandle;
begin
  FHandle := CreateFile(
    PChar('\\.\' + FPort),
    GENERIC_READ or GENERIC_WRITE,
    0,
    nil,
    OPEN_EXISTING,
    FILE_FLAG_OVERLAPPED,
    0);

  if FHandle = INVALID_HANDLE_VALUE then
    raise EComPort.Create(CError_OpenFailed, GetLastError);
end;
