Virtual COM Port Driver
Create virtual serial ports and connect them via virtual null-modem cable

Virtual Serial Port Driver by Electronic Team allows creating a large number of virtual COM ports and gives you the great possibility to fully emulate serial port behavior. Virtual Serial Port software is not just a simple COM port emulator. It provides flexible port creation, management, and removal, allows testing serial software, supports control lines and high speed of data transfer between virtual COM ports. Various applications can exchange data using virtual serial ports connected with a virtual null-modem cable. Serial data sent from one port to another will be received momentarily.

Virtual Serial Port Driver main features

Virtual COM Port Driver is a powerful technology designed specifically for those who develop, test, or debug serial port software and hardware. This solution will provide your system with as many virtual COM interfaces as you need.
Add more COM ports

Easy way to add more COM ports in the system

Virtual Serial Port Driver is a software solution that doesn't require any additional hardware and cables. No need to occupy real COM ports. Virtual ports fully emulate real ones, so that applications don't see any difference.
Unlimited number of COM ports

Unlimited number of COM ports

With Virtual Serial Port Driver, you can create as many pairs of virtual ports as you need. Any data sent to one port in the pair is momentarily received by the other port.
Full serial emulation

Full serial emulation

Virtual COM ports operate the same as real ones and any application can work with them as if they were real physical ports on your computer. Each pair of virtual serial ports supports all hardware signal lines and allows setting any type of signal line connection. If the emulated device works at a fixed speed, there is no problem to emulate the needed baud rate with Virtual Serial Port Driver.

Virtual Serial Port Driver PRO features

Virtual Serial Port Driver PRO is an efficient and complete software that works based on the functionality of Virtual Serial Port Driver. The program makes it possible to create bundles of virtual serial ports and put in place custom parameters, making it a solution that can be used in various scenarios. Virtual Serial Port Driver PRO allows you to manage real and virtual COM ports easily and conveniently.

Splitting and joining COM ports

Splitting and joining COM ports

With Virtual Serial Port Driver PRO, you can split physical serial ports (such as COM 1) into multiple communication ports (COM2, COM3, COM4, and so on) which are shown in the system as same copies of a hardware serial interface. Also, the software solution allows hardware serial ports to be shared among several applications. The software solution will make it possible to link multiple real physical COM ports to a single virtual port. When a serial application is connected to this virtual port, it will receive data from all connected COM ports at the same time.
Creating bundle connections

Creating bundle connections

This unique functionality that the software PRO version offers enables you to set up and manage complex serial ports bundles. This implies that you can transmit serial data in and out by a limitless number of physical and virtual COM interfaces. Serial data will be received by a COM port the ‘IN’ side and then redirected to all COM ports at the ‘OUT’ side of a bundle and vice versa.

More so, creating Main port for each side of a bundle (In/Out), enhances the process of hardware control lines management.
Switching ports automatically

Switching ports automatically

In case the number of ports your application can only work with is limited, a switcher, which is a unique feature of Virtual Serial Port Driver PRO, can be used. This option makes is possible for you to connect multiple physical ports to a single virtual port (you also have the option of assigning the same name to all the ports), and set up a switcher to this virtual rs232 port in via the appropriate app.

Whenever your program needs to connect to a serial port, the switcher will go ahead to identify a non-occupied COM port in the list of connected ports and make it available to the app. This implies that your program will automatically interact with any free serial port as though they were connected to the same port.
Merging COM ports

Merging COM ports

Virtual Serial Port Driver PRO’s new advanced feature allows you to add an unlimited number virtual COM port to single serial port bundle not divided into ‘IN’ and ‘OUT’ sides. Whatever is set to one port will be replicated to other real and virtual ports of the bundle. Thanks to this breakthrough feature, every application or device can now exchange data with multiple applications/device at the same time.
Advanced COM port testing

Advanced COM port testing

Another extra useful Virtual Serial Port Driver feature is Loopback. With its help, you can create fully-functioning virtual COM-port bundles with a circuitous data bearing. Technically, the ‘IN’ side of this type of bundle is linked directly to its ‘OUT’ side. So, whatever data you’ll send, the very same one you’re going to get. Or not. That will depend on your port’s correct operation.

The frequently asked questions

A virtual COM port is a software package emulating a hardware serial port in such a way that your operating system and all applications recognize it and interact with it as though it were a real COM interface.
A virtual COM port is often used for connecting some specialized COM-enabled equipment (commercial, laboratory, control system devices, etc.) to modern desktop computers and laptops that don’t have a physical serial port.
In order to create a virtual serial port, do the following:

  1. Download the dedicated software and install it on your PC.
  2. Start the app and head to the "Pair" tab.
  3. Click "Add a new pair" and select the ports from the drop-down menu.
  4. Click "Create".
Now you can see the two newly-created virtual serial ports in the Serial Ports Explorer and Device Manager of your computer.

Note: The software lets you create as many virtual COM port pairs as you want.

    We are using VSPD for testing out Geographic Information System software connectivity with a virtual GPS (software simulation). The GPS emulator is simulating the output we normally receive from a GPS navigator.
