The Virtual Serial Bus Enumerator 9 (Eltima Software) driver is a software component created by Eltima Software that allows the emulation of virtual COM (serial) ports on a Windows system. These virtual ports are often used for applications that require serial communication but don't use actual physical serial ports. Instead, they create "virtual" COM ports that can be used by software just as if they were connected to physical devices.
Eltima Software is known for its tools like Virtual Serial Port Driver, which allows users to create and manage virtual serial ports, enabling communication between software that relies on serial communication, even when no physical serial ports are available.
The Virtual Serial Bus Enumerator 9 driver is a part of this software package and helps manage the virtual ports created by the software.
