It is very simple. You need a serial
to usb convertor. There are a lot of these things available, Can be in one unit or incorporated in the cable connector.
Cost are about € 10,-.
But there is a small risk of damage to your computer because of different voltage.
The best way is to use an optical seperated connection. These are available from Actisense. Or a simple magnetic separation is also possible with an Adum4160.
If you use Windows look for a serial/usb convertor with a compatibel chipset.
