Let me see if I got this. Your legacy device has an RS-232 port e.g. with a
DB-9 connector on it. You want to talk to it via a USB port.
If it's just that, then there are a number of USB-to-Serial converters.
Keyspan is one.
Digi sells RF modems which would let you make the device wireless.
But, if you're trying to network the device, then you'd need something else.
