Hello everybody.
First I want to apologize for some spelling errors or words used in a wrong context, I am writing from France (near Strasbourg).
I programmed an application in Delphi 6, which writes data to the 8 standard output lines of the parallel port (it does not read anything), operating an electronic "device" (to say it simply). I made the connections indicated on another page of this site, by "John Sawyer" (who built a dongle which simulates a parallel printer), so I don't need any special dll because the standard handshaking is simulated this way (I know for example that Oxford Chipsets, as used by Lindy in particular, are not compatible with inpout32.dll) . The work is done under Windows 2000 Workstation (32 bits ! Yes, some people are still using it) via the WIN32API (SysUtils in Delphi) using CreateFile, WriteFile and CloseHandle. The system works without any problem.
Now my question : I built my system for demonstration purposes and perhaps one day it will have to be used on a newer machine running a 64 bits version of Windows. What will happen ?
Thanks for any answer ...
