Years ago I sold circuit board with mega8s 9 them. I had a friend (who I have no way of reaching now) who made a windows software that used a basic parallel programmer so that customers could change settings on the board.
That was 15 years ago, and of course, nothing has a parallel port on it anymore.
The software is locked in to use lpt1 only.
So I need to find a way to communicate with the boards using USB, but configure it to lpt1.
In device manager I can try to change the port of the USB programmer, but none of the PCs I've tried list the printer port as an option.
I'm pretty ignorant when it comes to the workings of the ports and such.
Is there any way to make this work easily that I could give customers to allow them to interface with my PCB?
