Bematech Virtual Serial Port Driver is a software utility that creates virtual serial ports on a Windows machine. These virtual serial ports allow communication between devices or software applications that expect to use traditional serial (RS-232) communication through COM ports, but without the need for physical hardware ports. It's typically used in systems where serial communication is required but physical serial ports are not available, or to simulate a serial connection for software development, testing, or specialized applications.

In the case of Bematech, this virtual serial port driver is often used in conjunction with Bematech's POS (Point of Sale) systems, barcode scanners, receipt printers, or other peripherals that communicate via serial ports.
