A virtual serial port emulator provides an excellent way to develop, test, and debug applications on computers with serial ports.
These days, many computers don't have a serial port, which makes the process difficult for developers.
So, if you want to create virtual COM ports on a machine running on Windows 7, 10, or 11, use a reliable, feature-rich serial port emulator.
For this, we’ve compiled a list of the best virtual serial port emulators with their features along with a data table. This will make it easier for you to assess and choose suitable software based on your specific needs.

Virtual Serial Port Driver is a software package developed by Electronic Team that functions as a virtual COM port emulator on Windows machines. The software enables you to create virtual COM ports that you can connect in pairs by using a virtual null-modem cable. Every virtual serial port that you create will communicate with your serial applications as if they were actually physical ports.
The advantages of RS232 Emulation software by Electronic Team:
This Virtual Null-modem Software runs on Windows (32-bit and 64-bit): 7/8/8.1/10, Windows Server 2012/2016/2019
You can download Virtual Serial Port Emulator for a fully-functional 14-day free trial. The standard version of the software costs $139.95.
VSPD PRO offers unique features that enhance the utility of your serial applications and devices:
Like the standard version of Virtual Serial Port Driver, the Pro edition runs on Windows (32-bit and 64-bit): 7/8/8.1/10, Windows Server 2012/2016/2019
The Virtual Serial Port Driver PRO license would cost $199.95. 14-day free trial

Choosing the handiest and suitable software solution depends on areas and conditions of usage. Here are a few situations where virtual serial ports can be useful.
1. The absence of a serial port.
Many of the computers that manufactured today are not equipped with any serial ports at all. Some machines take it a step further and do not have ports of any type, relying on wireless connectivity to peripheral devices.
The reduction in reliance on COM ports in machines and devices used for general purposes has not eliminated the requirement for serial connectivity. Many special-purpose devices still make use of serial interfaces to communicate with computers. Some examples are industrial automation monitoring devices, medical monitoring equipment, and specialized laboratory equipment.
2. Sharing a serial monitoring device.
If you have a serial monitoring device in an industrial production facility, it may be transmitting data used as input for several different applications. Creating virtual serial ports from a single port lets all of your applications receive their data at the same time.
3. Accessing multiple serial devices.
Network-attached serial devices can be assigned virtual RS232 ports that can then be merged into a single virtual port that can be used by your application.
So on these occasions, the best choice is virtual serial port emulator software. A benefit of a paid solution is that you receive regular program updates and customer support for your money. This can be a determining factor if you are doing serious development and want the most up-to-date null-modem emulator application available.
The preceding comparison of virtual null-modem software tools indicates that Electronic Team’s Virtual Serial Port Driver offers more features than the other solutions. Ease of use, quality customer support, and a focus on data protection are some of the advantages of this product. It also features a user-friendly interface that makes it an easy task to create and delete virtual COM ports.
The extended capabilities of the PRO version make this flexible software application an effective and powerful tool for developers or users who need to work with serial devices.
These are just a few ways that virtual ports can be used. If you work with serial devices or applications, a serial port emulator like Virtual Serial Port Driver can be an essential component of your software toolbox.
