Assuming the software wants to talk to a serial port, and the device
only has a USB port, is there a way to make them talk to each other?

If the kernel supports this UPS, then when the UPS is plugged into a USB port, the kernel should create some devices for software to interact with it. If the UPS requires a serial-port device then I'd expect the kernel to create a serial port for it.

What does the kernel do when you plug the UPS into a USB port?

You will need USB Serial Converter support compiled into your kernel (probably default for RH8).

# USB Serial Converter support

When you plug in your "USB-serial" device, serial device(s) will "magically appear" in your /dev filesystem. For my handspring cradle, it is /dev/usb/tts/0 and /dev/usb/tts/1. Then you need to get software to talk to one of these. Try some googling.
