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. 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. Network-attached serial devices can be assigned virtual RS 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.

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. Electronic Team, Inc.

The Best 7 Virtual Serial Port Emulators for Windows Nowadays engineers who are developing these serial devices or applications that interact with them require the ability to test and debug their products before releasing them to the public. Best 7 Virtual Serial Port applications We have compiled a list of the top virtual serial port driver applications that are on the market.

If you require the creation of virtual COM ports on a computer running the Windows 7 or Windows 10 operating system then read on. One of these software solutions may be just what you need to help you create virtual COM ports. 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.

It is fairly easy to install, configure and use the software; we have run it on different Windows versions and experienced no problems at all. If you like the idea of using a serial port simulator but are not sure which solution to choose, an open source kernel-mode virtual serial port driver com0com will definitely be a good choice.

The program is able to provide a COM interface for device emulation apps. What this means in practice is that a device emulation program connects to one port of a serial port pair while the other port is used by Windows app that needs to talk to the device. This way, for example, you can share faxes over IP. Com0com support for Windows 10 is another advantage of the app. Still trying to find an efficient emulator for serial communication?

Easy-to-use Software developed by AGG is designed to help you resolve any serial communication issue. This free application lets you create a virtual copy of a hardware null-modem cable with DB or DE-9 connectors. More than that, the app works exclusively in user-mode which ensures the stability of its performance. If all you need is a handy solution for establishing seamless communications between two serial apps, you can try Virtual Serial Port Kit.

This software will let your communications programs talk to each other over a reliable virtual COM port connection. The main goal of the tool is to provide your system with virtual COM interfaces through which serial apps can enable their two-way data exchange.

The scenario is extremely simple, the software just creates two virtual serial ports exact copies of hardware interfaces on your computer, let's call them COM1 and COM2, and then one of your apps connects to COM1 and the other one occupies COM2. The data transmission starts once the virtual ports are opened on both sides by the apps. The additional advantages offered by Virtual Serial Port Kit include support for several null-modem pinouts with different handshakes used for the communication process and the ability to emulate loopback plug.

The adapters change the pin configuration from straight-thru to null modem. So if null modem adapters are installed on both sides, the pins will line up like a straight-thru cable again. One downside of null modem cables is their limited distance. AT cables can easily cover distances of up to feet while null modem cables have a maximum distance of feet.

This foot limit also applies when using a null modem adapter with a serial cable. Internet Explorer will soon be unsupported on this site.
