There are network to serial apps, servers and more on the web. I don't see enough detail to offer much more but my cheat that always works is to put a small PC with the app that gets to the device on the network then VNC to that PC when needed.

Works every time.

Part of my apps for decades used many many serial port systems. It's rather a well beatup system but the details are so sparse that I'm going with my homerun play.
