How to Bypass a Parallel Port Dongle

What do you do when it's time to upgrade an ancient system? Put an image in an emulator and see what it does. But what if the program requires a hardware dongle on the printer port? Therein lies a story.
This software was built using a programming language called RPG ("Report Program Generator"), which is older than COBOL (!), and was used with IBM's midrange computers such as the System/3, System/32, and all the way up to the AS/400. Apparently, RPG was subsequently ported to MS-DOS, so that the same software tools built with RPG could run on personal computers, which is how we ended up here.
This accounting firm was actually using a Windows 98 computer (yep, in 2026), and running the RPG software inside a DOS console window. And it turned out that, in order to run this software, it requires a special hardware copy-protection dongle to be attached to the computer's parallel port! This was a relatively common practice in those days, particularly with "enterprise" software vendors who wanted to protect their very importantTM software from unauthorized use.
