I could find lots of drivers for other manufacturers products labeled as a HPI56A but none that would work with a HPI56A3 modem.
I cannot confirm my modem is actually made by Pro-Nets as it is not marked on the card but the model number matches. I was unable to download the driver from their own website as the link was broken.
The attached (unsigned) drivers were installed by Windows XP automatically and so I am unsure how they work with other Windows OS's.
