If you use the Console port to manage CISCO devices, connect one end of the Console line to the Console port of the device, and the other end to the DB9 or DB25 interface of the computer.

DB9 and DB25 interfaces are generally only available on the desktop. We cannot debug devices around the desktop every day. Instead, we often use laptops to debug devices, many laptops do not have the DB9 and DB25 interfaces, while USB is the most interface on the laptop.

The DB9 interface uses the RS232 serial port (comport) protocol. Therefore, you can buy a USB-to-serial port (USB-to-RS232) adapter and install the RS232 serial port driver on your computer, activate a comport on the USB port of the notebook.
