VBX registration is non-functional in VB4 16-bit (VBRegisterModel is a no-op, VBGetModelInfo never called). Native Delphi component avoids all DLL/export/registration issues — compiles directly into the IDE. TKPComm is a TComponent descendant calling the Windows 3.1 comm API directly. Uses RegisterClass/CreateWindow for WM_COMMNOTIFY dispatch with the component instance pointer stored in cbWndExtra. Includes a test application (KPTEST) with send/receive UI built entirely in code.
