What is COM0COM - Serial Port Emulator Driver?

COM0COM is a virtual serial port emulator for Windows. It allows you to create virtual serial ports on your computer, which act like real physical serial ports (COM ports), but no hardware is required. This software is particularly useful when you need to test serial communication between software applications or when you want to simulate the interaction between serial devices without using physical hardware.

COM0COM essentially creates pairing virtual serial ports that communicate with each other. For example, you can create two virtual serial ports (COM1 and COM2) where data sent from COM1 will automatically be received on COM2 and vice versa. This is commonly used in situations where you need to test software that communicates over serial ports, such as modems, barcode scanners, or other serial devices, without requiring real hardware.
