Naming your serial ports with udev Brief UART is still a very common way to communicate with embedded systems, in fact, I would say that it is the most common way. When looking around in my lab, I can see that I have four different development boards/projects connected via UART to my computer. Two of them even use more than one port.
My point is that when you have many serial ports connected to your computer, it can be hard to keep track of which port is which.
