In depth

A closer look at (USB) Serial Port Watcher

The Serial Port Watcher application was designed to be a small program that watches your serial ports and tells you when one becomes available Namely the relative unpredictability of what COM port will be assigned to a USB Serial dongle when I plug it in - you plug it in, Windows tells you that its connected, and then you have to dig through the Device Manager in order to figure out what port was assigned. Instead of going through that, this program runs a check every few seconds and lists all the ports that are currently available (from COM1 to COM254). You plug in your USB dongle, and within a few seconds you will see its associated COM port pop up on the list.
