Virtual Serial Port Driver

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

Common problem

Modern computers mainly don't come with a physical COM port, however sometimes you need to use a COM port connection. That's where serial port emulation comes in handy.

How Virtual Serial Port Driver solves it

You can easily emulate a null modem connection to allow applications exchange data without any additional hardware. Create virtual ports and give them custom names. Everything sent to one port by an application will be received at another end of the pair by another application.
Thinking about integrating our functionality into your own industry-specific solution?
Eltima Port Virtualization Technology is just what you need. Thousands of successful companies worldwide have already experienced the undeniable benefits and advantages of powering their software and hardware products with our advanced technology.

Virtual Serial Port Driver main features

Easy way to add more COM ports in the system

Serial port emulator 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

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 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 you 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 serial port emulator.

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

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 virtual COM ports to a single real physical port. When a serial application is connected to this real port, it will receive data from all connected COM ports at the same time.

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

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

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.
