I’ve faced similar challenges when trying to set up virtual COM ports for serial communication. At first, I tried a few free tools, but I kept running into issues, either the ports weren’t recognized by my applications, or the connection would drop randomly.
After some research, I came across https://www.virtual-serial-port.org/ and it solved all my problems. With this tool, I could create virtual COM port pairs and both of my applications recognized the ports without any trouble. What I really like about it is the stability - it ensures consistent data transfer without the random disconnects I experienced with other tools. Plus, it’s compatible with Windows 10 so you shouldn’t run into any compatibility issues.
