The official UserPort homepage
This is the official homepage for UserPort. UserPort is a kernel mode driver for Windows NT/2000/XP that gives user mode 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 user mode programs on these operating systems.
The driver can be used for the following purposes:
- To run software on Windows NT/2000/XP that normally only runs on Windows 95/98/ME.
- To easily access hardware like the parallel port and other I/O ports.
