They look similar but a VGA port has 15 pins and a serial port has only 9. Serial ports like this one were really common before USB was used. You would plug peripherals into it kind of the same way you use a USB port. Mice were probably the most common use, but you could plug a lot of different things into them.
Honest question, what do you use these ports for apart from VGA? I never used anything but VGA but these ports look the same.
