If you are a Windows 10 user and need to add a virtual COM port in Device Manager to solve a real problem, you can add a virtual serial port through USR IOT’s Virtual COM Software, which is designed to create an unlimited number of virtual COM ports via Serial server connections communicate with each other.
Let me take the USR-N510 of USR IOT as an example to introduce the operation steps for adding a virtual serial port.
Download USR-VCOM
You can find the Virtual COM Software in Serial to Ethernet => USR-N510 => Downloads on the www.pusr.com and download and install it on your computer. Through USR-VCOM software users can set up connections between USR modules and virtual serial port to solve the problem that traditional equipment PC software used in serial port communication way.
Connect to Serial to Ethernet Converter
1. Hardware connection:
For USR-N510-H7 products, the USB-RS485 serial port cable is connected to the N510 serial port, pay attention to the 485 wiring sequence, the USB-RS485 A cable is connected to the A terminal of the N510 serial port, the USB-RS485 B cable is connected to the N510 serial port B terminal, and the USB head is inserted into the computer USB port.
The N510 network port selects a network port to connect directly to the computer network port through a network cable. After checking all connections, use a 12V power adapter to power the N510.
2. Indicator status:
1) POWER light: power indicator light, as long as the power connection is normal, the indicator light will be on.
2) WORK light: Work indicator, N510 working status indicator, N510 is working normally, and the indicator is flashing.
3) 485TX light: serial port 1 sending light
4) 485RX light: serial port 1 receiving light
3. Computer settings:
1) Computer local connection, IP settings and N510 IP same network segment, N510 default IP is 192.168.0.7, gateway 192.168.0.1, computer local connection IPv4 set static IP, 192.168.0.201, subnet mask 255.255.255.0, gateway 192.168 .0.1. Disable other network cards.
2) Turn off the firewall on the computer.
3) Check the COM port number of the USR-RS485 serial cable
Click the computer, right-click the mouse, click the device manager, check the port, confirm the COM port number of the USB-RS485 serial cable, someone tested the computer is COM3.
4) Download and open the H7 series configuration software to configure the serial port server.
Add virtual serial port
1) Open the USR-VCOM you downloaded.
2) You add a virtual serial port COM1, and select TCP Client as the network protocol. The remote IP is filled with the IP of the N510, and the remote port is filled with the port 23 of the N510.
Open the test software «USR-TCP232-Test.exe».
We can open the RS485 serial port and the virtual serial port COM1, and keep the debugging serial port parameters consistent with the RS485 serial port parameters, such as baud rate, data bits, stop bits, and parity bits. In this way, one-to-one data transmission between two serial ports can be realized.
The various USB interface modules made by Technological Arts are based on the popular FTDI chip FT232RL. Usually, Windows will recognize them when you plug them into a USB port on your computer. If it doesn’t, you will need to download and install the appropriate driver from the FTDI website (www.ftdichip.com). Drivers are provided for various versions of Windows. Download and install the correct version for your computer’s configuration before proceeding.
Now connect a USB cable between a USB port on your PC and the USB interface module you are using. Windows should report a new device has been found and proceed to initialize it. To determine which virtual COMport it has been assigned to, right click the MyComputer icon on your Windows desktop, and select Properties from the popup menu. Next, click on the Hardware tab, and click on the Device Manager button.
Click on the + sign next to Ports (COM & LPT). The list of available ports will be revealed. You will see one entitled USB Serial Port, with the assigned COM port number identified in brackets.
To work with most of the tools you are likely to use with microcontrollers, the COM port should be 1, 2, 3, or 4. If it is higher than COM4, you’ll probably want to change it. Do this by right-clicking the line “USB Serial Port” and select Properties from the popup menu
Click on the Port Settings tab, and then click the Advanced… Button.
Select the COM port Number dropdown box and select a COM port number 2, 3, or 4 (usually COM1 is already in use).
The port number may be reported as “in use” but you can disregard that at this point, if you know that nothing is currently using it.
Click OK, and if Windows warns you about a duplicate, ignore the warning and click Yes. Click OK and then OK to the port settings. Then close the Device Manager window. If you want to confirm the port change has indeed been made, click on Device Manager again and check the listed Ports. Now close the System Properties window.
At this point, you are ready to use the virtual COM port in any application!
Note that, if you unplug the USB device and plug it back in later, Windows will still remember the COM port assignment, so you won’t need to go through this procedure again. However, there is a known Windows issue that affects most applications. The virtual COM port will be removed from the device manager when the USB cable is unplugged, even if an application has the virtual COM port open. The virtual COM port will not be accessible even after the virtual serial device is reconnected unless the virtual COM port is released by the application prior to the reconnection, which may require closing the application first. It is therefore recommended that the application be closed before the USB device is unplugged.
Most modern desktop computers and laptops no longer have the old school DB9 RS-232 serial ports (COM ports) that were traditionally used to connect directly to the hardware used in commercial, laboratory or industrial safety and control systems. In many cases, even if they do, the number of available ports is very limited. This can be problematic if you still rely on legacy software applications that communicate through those now non-existent (or very limited) serial ports. The challenge here is different than just converting a serial device’s interface to a USB or Ethernet interface. This is because the legacy software doesn’t know how to recognize or read USB or Ethernet data — and resurrecting the software engineer that originally coded it probably isn’t an option.
We all need to upgrade computers from time to time to keep up with the latest OS and security requirements, not to mention just getting that new car smell. However, that doesn’t mean your legacy serial software assets should suddenly be worthless…does it? We say down with obsolescence and waste!
We’re going to help you get more life out of your serial system while keeping your computer in the 21st century. NetBurner provides a free virtual COM port application that creates a virtual COM port that can be used to transmit serial data over a network (Internet or LAN) to NetBurner Serial to Ethernet Servers or System on Modules. This saves time and money by allowing you to continue using your existing legacy applications.
Important Note: This tutorial deals exclusively with a virtual COM port implementation that is used with NetBurner devices. If you are looking for a native software solution to create virtual COM ports for use with other systems or hardware, we suggest the Virtual Serial Port over Ethernet Connector or the Virtual Serial Port Driver from our partners at Eltima Software. They are both incredibly stable and versatile utilities that support various Windows versions, up to the latest Windows 10.
Hardware and software required for the example
- A Serial to Ethernet adapter. Any of NetBurner’s serial to Ethernet solutions will work.
- A serial communications program, such as the MTTTY serial terminal provided on our website.
- Virtual serial port software, such as NetBurner’s Virtual COM Port Driver provided on our website. (License Terms)
- One serial to USB converter dongle, such those made by Sabrent for sale here.
Our test setup
We’re going to show you a very basic virtual COM port configuration to display the ins and outs of getting a virtual COM port running. Please note that the virtual COM port driver provided on our website can only be used with NetBurner’s serial to Ethernet (S2E) hardware and System-on-Modules. To set up a virtual serial port configuration that can be used with any type of device over a network, we recommend the Virtual Serial Port over Ethernet Connector from our partners at Eltima Software. This application allows for the creation of any number of virtual COM ports with preassigned parameters. It can be used to establish a connection with hardware serial device servers over an Ethernet connection, as well as to create links with virtual serial ports created on other computers.
In our scenario, we will run an instance of the MTTTY serial terminal application to represent both ends of our communication path. First, it will represent the “remote client” that is connected to the NetBurner serial to Ethernet device through the serial to USB converter. Second, it will represent the “legacy serial application” that is sending and receiving data to this device through the virtual COM port.
We will start by creating a virtual serial port on COM20. This will allow us to send data from the ” legacy serial application” MTTTY instance to the NetBurner serial to Ethernet device over an Ethernet connection. The NetBurner device will then send this data out of its own serial port (DB9) back to the laptop. This data will be read using the USB port on the laptop with the help of a USB to serial converter. Finally, we will use the “remote client” MTTTY terminal to read the data from our USB converted serial port, COM6. This communication path is bi-directional. This means that data sent to one MTTTY terminal instance will show up in the other, and vice-versa.
How to setup the virtual COM port driver
- Install the Virtual COM Port Driver software. The default installation directory for the software linked above can be found at C:\nburn\VirtualCommPort. From here, execute NBVirtualCommPort.exe. The application window will open…we’ll come back to this shortly.
- Before we go further, we will need to know the IP address of your device and the listening port number. With NetBurner devices, finding the IP address is as easy as using our IPSetup tool’s search ability to discover our device on the network. IPSetup can be found in the C:\nburn\pcbin directory of your install, or just use your operating system’s search utility to find it.
If you are new to NetBurner products here’s a quick guide to help you use IPSetup. First, make sure your NetBurner S2E device or System on Module is connected to your Ethernet router or LAN. In our example, we use the SB800 EX. Second, power your devices either with an AC wall wart or via USB (if you are using a development carrier board, and have the jumper configuration setup to do so).
Open the IPSetup software. Your device should appear in the “Select a Unit” field, but if not click “Search Again” and wait for it to show up. If your device supports WIFI, clicking the “+” sign will expand the device’s entry to reveal the unit’s current IP address. Otherwise, it should be listed on the first line of the device entry. In the figure below, the SB800 EX shows an IP of 10.1.1.130. Jot down this IP address to use later.
- Now we need to go to your device’s homepage and discover its listening port. You can simply click “Launch Webpage” in IPSetup or type the IP of the device into your favorite browser. Click the “TCP” hyperlink in the menu. The figure below shows the “TCP” page for our SB800 EX, which has two serial ports, Port 0 and Port 1, respectively. Jot down the listening port for serial port 0.
- Back in the Virtual COM Port application, click on “Add” in the Virtual Serial Port dialog box, which will bring up the “Edit Connection” window.
- Next, from the “Select serial port” drop-down menu, select a COM port to associate the virtual COM port with, and give it a new “Connection Name”. In this case, we chose COM20 and named it “Client_COM20”. Then, in the box labeled “Remote host name/port”, enter the IP address of your NetBurner device followed by the listening port determined during the previous steps.
- Click “Add”, verify that the entry was added to the list, and then click “Apply”.
- Now we can see that our new virtual COM port has been successfully added to the main Virtual Comm Port application window.
- Open two Multi-threaded TTY windows (the MTTTY serial terminal application). One window will be used for the USB Serial port connection, and one window will be used for the virtual serial port. In our image below, COM20 was the virtual COM port we had set up, and COM6 is connected directly to our device via a serial port (in this case converted from the USB port- Universal Serial Bus).
- Click the “Connect” button on both application windows, and send data from the virtual serial port or USB serial port to confirm data is going back and forth.
Congratulations! You have now set up and tested your virtual COM port. We hope that you can see how this example can be expanded upon to incorporate your own legacy serial comm applications to work with newer computers that either have too few DB9 RS-232-style ports or none at all.

Через com порт ранее подключали модемы, мышки. Сейчас он используется для соединения с источниками бесперебойного питания, для связи с аппаратными средствами разработки встраиваемых вычислительных систем, спутниковыми ресиверами, кассовыми аппаратами, с приборами систем безопасности объектов, а также с многими прочими устройствами.
С помощью COM-порта можно соединить два компьютера, используя так называемый «нуль-модемный кабель» (см. ниже). Использовался со времен MS-DOS для перекачки файлов с одного компьютера на другой, в UNIX для терминального доступа к другой машине, а в Windows (даже современной) — для отладчика уровня ядра.
Но в сетевом мире через com порт подключаются к консольному порту сетевых устройств (коммутаторов, роутеров, таких брендов как Cisco или Juniper)
Какая схема подключения к коммутаторам через последовательный порт. Есть переходники, например от фирмы st-lab На одном конце USB который вы подключаете к компьютеру, а второй это com порт.
Далее к ком порту подсоединяется вот такой шнурок, com порт, а с другой стороны LAN RJ45, и вся схема дает нам один большой шнурок USB to LAN.
К сожалению в Windows подключенные устройства, usb to com не всегда автоматически устанавливаются в системе, и приходится искать для них драйвера. Если вы покупали его сами, то в комплекте шел диск с драйверами, и можно воспользоваться им, если его нет, то смотрим как найти драйвера.
Открываем диспетчер устройств в Windows. Если не знаете как, то нажмите CTR+Pause breake, либо нажмите Win+R и в окне выполнить введите devmgmt.msc. Как видите у меня в разделе Порты (COM и LPT) нашелся на третьем COM порту неизвестный провод, и драйверов для него не нашлось у системы, о чем говорит нам желтый значок.
Переходим в свойства данного устройства и выбираем ИД оборудования, у вас будет, что то по типу usb\VID_067B&PID_2303&REV_0300, вот его вы копируете и ищите в гугле или яндексе.
После чего щелкаем правым кликом по устройству в диспетчере устройств и выбираете установить драйвера, указываете до них путь и ставите, если все ок, то у вас пропадет значок предупреждения.
Далее вы уже можете использовать возможности com порта, с помощью таких утилит на подобие Putty, где вы выбираете пункт Serial и указываете нужный порт Com порта, посмотреть его можно в том же диспетчере устройств.
Надеюсь вы научились и разобрались как подключать com порт usb в Windows.

Android devices are becoming more popular every day. Even if you don’t own one yourself, chances are that one of your friends or business associates have at least one Android phone among their mobile electronic devices. The popularity of Android devices is driven by their affordability and ability to be easily customized. Android devices provide the user with multi-tasking capabilities and are tightly integrated with all of Google’s services.
If ports COM & LPT are not shown in the Device Manager of your Windows 10 system, you can install Virtual COM Port Driver and solve this problem once and for all. This software is designed to create an unlimited number of virtual COM port pairs communicating with each other over a virtual null-modem connection.
Virtual Serial Port Driver
In addition, the program offers a vast array of configurable options that can be especially useful for testing serial software and hardware.
For example, the utility lets two applications share data over virtual COM ports in such a manner that everything written by one program will immediately appear in the other one (connected to the other end of the virtual serial port pair).
Now, Let’s see where Windows 10 COM Port Driver software will be a really big help. You can use the software for a variety of purposes, including:
Pro version of Virtual Serial Port Driver
For those of you who are looking for a simple way to create not only virtual COM port pairs but also their bundles with various custom parameters, the app developers offer the Virtual Serial Port Driver PRO version. This edition is tailored for professional use by serial port software and hardware developers and testers.
The utility comes with a range of advanced features like:
You can easily split a single real RS232 port into multiple virtual COM ones that will fully emulate the physical port. Also, you’ll be able to join multiple real port data streams into virtual one which will be directed to the required app or device.
Virtual Serial Port Driver Pro makes it possible to create complex port bundles where multiple virtual and real serial ports can exchange the incoming data with all the other ports added to the bundle at a time.
Anytime your application needs to connect to a serial port, the switcher option will link it to a COM port being currently free. For this, you just create a bundle of virtual COM ports that will emulate a single real one. By communicating with one of the virtual ports, your app will, in fact, talk every time to the same real interface.
Alternatively to the third-party app, you may try the fix offered in Windows 10 OS:
Unplug your USB device and connect it to your PC again. Now your operating system should be able to recognize the device, and Virtual COM Port Driver should be loaded.
Frequently Asked Questions
1. How to find com port number in Windows 10?
Note: Only one Serial Port can be used per COM Port Number
Note: You’ll still need to restart your computer even if you change the COM port number back to the original number.
2. COM Ports Missing in Device Manager
Numerous people reported that they were unable to find the Serial Ports in Device Manager, and eagerly requested a solution.
What is the best way to locate the Windows 10 COM ports and solve the issue?
If you cannot see the COM ports, then you will need to open the Device Manager, navigate to the “View” tab, and click “Show Hidden Devices”.
The COM and LPT port options should then be visible, and the user needs only to expand the section to locate the COM ports.

In this article, we are going to discuss two ways to resolve the problem of the lack of COM ports on computers running the Windows 10 operating system. Windows 10 COM port issues plague many users whose computers have been designed without the inclusion of any serial interfaces. The absence of physical COM ports can hinder a user’s ability to make use of computing peripherals that transmit their data serially.
The way to resolve this issue is through the use of Windows virtual serial ports. It can be very frustrating to query your Device Manager with the expectation of finding COM ports only to find that they are not present. We are going to show you two different methods you can use to add COM ports to Windows 10. One is a procedure that employs the native functionality built into the operating system and the other uses third-party software.
Locating virtual COM port in Windows 10 can be a problem for users. You navigate to your Device Manager with the expectation to see the virtual COM port drivers that were previously loaded on your machine and find they are not there. The serial port option might not be available due to the installation of a Windows 10 update. The update may have impacted the ability of the virtual serial port drivers for certain devices to load by default. This poses a significant issue when you are trying to use these devices.

We provide a step-by-step procedure which can help you eliminate issues related to COM ports on Windows 10 in as little as three clicks. Read on to learn more about how to use this efficient virtual COM port driver for Windows 10.
When the COM and LPT ports do not appear in your Windows 10 Device Manager your ability to perform your work is negatively impacted. There is a way to resolve this annoying problem in a manner that will prevent it from recurring. The solution is to install the aforementioned Virtual COM Port Driver from Eltima. This application allows the creation of an unlimited number of virtual serial port pairs. The virtual COM port pairs employ a virtual null-modem connection to enable communication with each other.
Virtual Serial Port Driver
Users engaged in the practice of developing and testing serial applications and hardware will benefit from the configuration options that are possible through the use of Virtual Serial Port Driver. One example is the ability to allow two applications to share data via virtual serial ports. Connecting the apps with a pair of virtual COM ports lets the data written by one program be immediately made available to the other program. This can save significant time and effort when debugging and testing serial apps and devices.
Step-by-step guide to add virtual COM port Windows 10:
Following these steps with Virtual Serial Port Driver (VSPD) will enable you to easily create virtual serial ports on a Windows 10 machine:
There is a fix to the problem of mounting virtual COM ports in Windows 10 that does not require the use of a third-party app. These are the steps to follow to use the Windows 10 operating system fix:
How to change COM port settings in Windows 10
Some software applications are designed to only operate with designated serial ports. If you need to work with this kind of program, you may need to know how to find port numbers in Windows 10 so you can modify them if necessary.
In many cases when working with older devices or applications, you will be called upon to change COM port numbers to successfully operate the programs and peripherals. Some legacy equipment is only capable of working with specifically named serial ports.
The following procedure allows Windows users to change the COM port number for any attached device.
Just follow these simple steps on a Windows 10 machine to change the default COM port number.
Tip: Here is what you can try if COM ports are not showing in Device Manager:
There are multiple scenarios in which you may need to assign a COM port to a USB device on your Windows 10 computer. Some devices need to have a COM port identifier that falls within a certain range, say between COM1 and COM4. Windows may have assigned a different identifier to the port which you will be required to modify. It’s a relatively simple procedure to perform.
Here is how to assign a COM port to a USB device Windows 10:
Following these steps will enable you to change the COM port identifier for USB devices attached to your Windows 10 machine.
Conclusion
Virtual COM Port Driver is an advanced way to add virtual COM port pairs. There are many instances where this Windows 10 COM Port Driver software can be instrumental when working with serial devices and applications. Some of the uses of the software include testing and debugging in usage scenarios that include:

Null-modem emulator [1] это драйвер виртуального последовательного порта Windows, работающий в режиме ядра (kernel-mode driver), с открытым исходным кодом, доступный под защитой лицензии GPL. Null-modem emulator позволяет Вам создавать неограниченное количество пар виртуальных COM-портов. Каждая пара COM-портов состоит из 2 COM-портов, виртуально соединенных друг с другом каналом данных. Выход одного COM-порта пары соединяется со входом другого COM-порта пары, и наоборот. Следовательно, можно использовать любую пару для соединения любого одного приложения, рассчитанного на работу с COM-портом, с другим приложением, также работающего с COM-портом, и они будут передавать данные друг другу.
Null-modem emulator может использоваться для предоставления последовательного интерфейса к эмуляторам устройств. В этом случае программа эмуляции устройства использует один порт пары, и другой порт пары может использоваться операционной системой Windows или приложением DOS, которое требует COM-порта для обмена с устройством. Например, прием/отправка факсов через сетевой канал IP: Вы можете соединить приложение Windows Fax с приложением t38modem [2] (T38FAX Pseudo Modem, это часть проекта t38modem) через пару виртуальных COM-портов.
[com2tcp]
Также Null-modem можно использовать для последовательного интерфейса к редиректорам COM-порта. Например, с приложением com2tcp [3] (редиректор COM-порта в сокет TCP, это часть проекта com0com [1]) Вы можете обмениваться через последовательный интерфейс с серверами TCP/IP (очень полезно для работы с модулями наподобие ESP8266 [4]). Если Вы чувствуете, что com2tcp это примерно то, что искали, но все-таки в нем нет каких-то нужных возможностей, то присмотритесь к проекту hub4com вместо него (например, для поддержки RFC 2217).
[hub4com]
Вместе с приложением hub4com [5] (HUB for communications, хаб для обмена данными, это часть проекта com0com [1]) можно несколькими приложениями обрабатывать данные и сигналы одного устройства с последовательным интерфейсом (например, несколько приложений могут использовать одни и те же данные от одного устройства GPS). Также можно использовать реальные последовательные порты находящегося в отдалении компьютера (подключенного через сеть), как если бы эти интерфейсы существовали на локальном компьютере.
Вы можете найти больше информации по использованию com0com и com2tcp в файле ReadMe.txt для com0com, ReadMe.txt для com2tcp, ReadMe.txt для hub4com и так далее на страничке проекта сайта SourceForge [1].
[Virtual Serial Port Driver]
Альтернативно можно для тех же целей использовать Virtual Serial Port Driver [6] компании Eltima Software. Это программное обеспечение позволяет создавать большое количество виртуальных COM-портов и дает Вам большие возможности для полной эмуляции последовательного порта. Virtual Serial Port Driver предоставляет гибкое создание порта, управление портами, удаление портов, что позволяет через виртуальные порты тестировать программы, поддерживать управляющие сигналы и высокие скорости передачи.
Основные возможности Virtual Serial Port Driver:
• Создание любого количество виртуальных COM-портов.
• Полная эмуляция настроек реальных портов.
• Управление всеми сигнальными линиями.
• Немедленное создание портов позволяет работать с портами, даже до того, как PnP manager определил только что созданные порты.
• Полная поддержка Windows 10.
[VIRTUAL NULL MODEM]
Для чего нужна утилита Virtual Null Modem? Допустим, что у вас есть две программы, которые вы хотите соединить между собой. Обычно вам необходимо два настоящих последовательных порта, соединенных нуль-модемным кабелем. Современные компьютеры обычно имеют в наличии только один порт, а ноутбуки не имеют и одного. При использовании программы Virtual Null Modem вы можете эмулировать нуль-модемное соединение, так что две программы на одном компьютере могут общаться между собой без дополнительного оборудования и железа.
