I did something like this with a box from Scannex.co.uk to extend a physical serial port to a Linux VM. On the VM I used socat to emulate a serial port that a legacy app "connected" to. Socat handles the transmission between the Scannex box and the remote systems (one is a traditional phone switch and the other is a POS system from Micros). The Scannex box has physical RS-232 ports and can create a server similar to a netcat server. It can even go over SSL if you have data security concerns.
Scannex has always had A+ support and continues to provide firmware updates for boxes that we've had for many years. The boxes are rock solid and largely trouble free once they are running. That said, they are very expensive, so they may not fit the bill depending on your application. You can probably do the same thing with a small Linux PC or maybe even a well-fitted Pi.
