However, this "direct" connection is not plug-and-play. The computer must recognize the Cisco device as a serial communications device. The Cisco USB Console Driver creates a virtual COM port on your PC, allowing terminal emulators (like PuTTY, Tera Term, or SecureCRT) to communicate with the hardware.

Version 3.1 is a significant release because it addresses compatibility issues found in newer operating systems, specifically Windows 10 and Windows 11, which older versions (like v2.1) struggled to support.
