RS232 was the universal/popular port back in the old days just like USB is today.

In short, all you need to know is...

Modern computers no longer have RS232 port (extinct just like VGA port is). So all you need to get is a RS232-to-USB converter. It's about $5 on eBay. Just search for: rs232 usb

When you buy it, you'll need to install it to Windows-based computer. Here's how...

Step 1:

Connect RS232 device into any USB port on your laptop/computer. Allow 20+- seconds for Windows to attempt to install drivers automatically.

However in 95% of cases, it will fail to automatically install the drivers. So you have to install drivers manually.

Here's how...

2) Install both driver packs below...
- Driver Pack 1
- Driver Pack 2
- Driver Pack 3

3) Restart your computer.

4) Connect RS232 device into any USB port. This time Windows will auto-install the drivers. You can verify a correct install going to Device Manager. Here's how...

Windows Vista/7/8/10:

Control Panel » System » Device Manager

Windows XP:

Control Panel » System » 'Hardware' tab » Device Manager

You should see something like this:
