There is now a version of the inpout libraryDLPORTIO, usable form Delphi 7 as I have shown before, also for 64 bit (Windows 7 and 8.1):

From Version 1.0.0.7, InpOut provides basic DLPortIO compatibility, for use with LCDSmartie etc.

To use with LCD smartie, take the 32bit DLL (in \Win32) and rename it to DLPortIO.dll
