Parallel port error

What program are you executing?
WinXP has nothing called IO.DLL. Did you install some sort of port access driver?
 

Re: Parallel port error

Hi , you can use USERPORT ,

UserPort.SYS is a kernel mode driver for Windows NT/2000 that gives usermode programs access to I/O
Ports. This makes it possible to access hardware directly from a normal executable in the same way as under
Windows 95/98/ME. This driver does not work on Windows 95/98/ME and there is really no need to run it
anyway because I/O ports are always granted to usermode programs on these operating systems.
The driver can be used for the following purposes:
• To run software on Windows NT/2000 that normally only runs on Windows 95/98/ME.
• To easily access hardware like the parallel port and other I/O ports.

enjoy it ...

The IO.dll may be unregistered in your PC or the DLL file is missing. If your PC BIOS does not support ECP mode (bi-directional), then it also causes such as problem. You may check it at BIOS setup > parellel port.

Visit www.geocities.com/bagtool/parallel_access.html
I just find it and the website may provide the info that you need in the parallel port
interfacing.

Parallel port error

I use that program in my internet coin program (posted recently). The io.dll is a free dll to be able to use the ports on XP, very neat and handy.
The problem is that the program is looking for that dll , you can just download it from the internet (just google it) ans save it in the same folder of the program or the windows/system32 folder.
I'm not expert in software so I don't know if is the right way or not but it worked for me.
 

Re: Parallel port error

why don't you try inpout32.dll

This comes free from **broken link removed** with source code and explanation how it works as well.

Cheers
