I converted the code to Delphi. It had some bugs in it but nothing major. At some point I kept getting blue screens (SYSTEM_SERVICE_EXCEPION with bugcheck 0x0000003B). It turned out that my trusty USB-->serial converter was misbehaving (Belkin F5U103v). Swapped it for a new one and all was fine! What I like about this library is that in combines Modbus TCP / RTU and ASCII in one library.
