Windows NT/2000/XP doesn't allow the DOS-based programs to access hardware ports directly. So, you shouls install MS-DOS-based environment (such as Win98/Me) in addition to WinXP to have the opportunity to run such programs.

Maybe the good solution is to boot from Win98 rescue disk to run the program.

Computer data storage, often called storage or memory, is a technology consisting of computer components and recording media used to retain digital data. In addition to local storage devices like CD and DVD readers, hard drives and flash drives, solid state drives can hold enormous amounts of data in a very small device. Cloud services and other new forms of remote storage also add to the capacity of devices and their ability to access more data without building additional data storage into a device.
