zI'm wondering if anyone has figured out how to get modern PCIe parallel ports into specific modes (spp, ps/2, epp, ecp) I am baffled by this, just when I think I figured out what is going on, suddenly I can't duplicate my results. I have searched all over the web for documentation and the closest I...

I really don't have a use for DLPortWriteULong anyway. I'm just happy to get it working! Thanks again for your help.

I finally got it working!!! Thank you for all your help here. It was a great help to get your demo working, because then I knew my parallel port was working with InpOut32 and that InpOut32 was also working. I got some help from Marc on the freepascal mailing list about calling C libraries from pasca...

It just occurred to me that your demo program is a dos command program.. I did get it to work. at first I was getting the same results but I was putting in port $378 using a $ to indicate hex, but then I remembered that's a pascal thing... so I put in 888 for the port (decimal of 0x378) and I'm happ...

I checked my bios settings, my parallel port is set to standard mode (SPP) I'm guessing that should work, it's how I always set my ISA cards. I guess it is getting to be old school, but it was such a convenient way to read a few bits and send out a few bits... no need to program an arduino and sever...

Phil, Thank you for the suggestions. I have tried both inp32() and Out32(), I get identical results. Perhaps you are on to something with the port mode. The parallel ports I am used to were the old ones that you could write to at any time.. then read back what you wrote, and if you forced high pins ...

Oh, I think I made a mistake and used X64 but it's an x86 program. It's the program that determines which version you use not the host computer I take it. I switched to inpout32 and now I can compile it AND run it... however I'm still not getting the expected results. I added isinpoutdriveropen() as...

well I'm maybe making progress... I hope. I did get it to compile! YAY. But I get a runtime error when I try to run my program... Boo! Please forgive me if posting my code inline is against some forum rules.. I'm just so close, yet can't quite get it to work. I get The application was unable to star...

This isn't really that big, I guess I can just paste it in here. I'm thinking I probably have the syntax wrong, this might be a delphi example, I don't know what the syntax would be for freepascal running in Turbo Pascal compatibility mode with the text based IDE. unit DLPortio ; interface Function ...

Thank you for any help you can offer. It's the last piece to the puzzle and I will have full functionality again if I can get it to work. Until I'm able to post files, I would he happy to email you the sample I have... I'm not sure where I got it from. There was mention of inpout32 here: http://wiki...

I have an old Turbo Pascal DOS program I am trying to port over to windows using Free Pascal. I have got everything working except control of the parallel port, which used to be so easy, but now I find it nearly impossible. I do not know if ImpOut32 (x64) will help me. I downloaded it and tried to c...
