Virtual COM Port Emulator

You don’t have any free serial ports left or you don’t have any serial ports in your system at all. In such situations Virtual COM Port Driver fits as a fiddle if you want to extend your capabilities and capabilities of your computer. Virtual serial ports, created with Virtual COM Port Emulator appear in the system like usual hardware one and the application working with them will never notice the difference. Virtual COM Port software gives you the ability to use several pairs of ports simultaneously.

What is Virtual COM Ports Driver?

It is a powerful tool to create virtual COM ports, which you need once you run out of physical serial ports. Considering that modern computers have at most one or two serial ports, knowing how to create virtual COM port with the help of a virtual COM port driver is essential. Virtual COM ports are usually used for testing/ debugging application by enabling them to communicate to each other.

How Virtual COM Port Emulator solves it

After virtual COM port download the software connects virtual serial ports via virtual null-modem cable, no additional hardware is required. An application at one end of this virtual bridge sends data to an application at the opposite end and vice versa.
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.

Advantages of Virtual Serial Port Driver

Your programs need testing/debugging

In order to test any application or emulator create two virtual serial ports COM3 and COM4 with Virtual СЩЬ Port Driver and connect them in a pair via virtual null modem cable. All data sent by the first application to virtual serial port COM3 will be received on virtual serial port COM4, and all data sent to virtual serial port COM4 will be received on virtual serial port COM3.

You need more serial ports in your system

With Virtual COM Port Emulation you will be able to create as many virtual serial ports in your system as your needs require. The connection between pairs of virtual ports is highly dependable so you can be sure there won’t be any data loss or connection will not break all of a sudden. You can give any name to the port you create you leave the same name real serial port has. In this case virtual serial port overlapping happens – when an application reaches to the real COM port through the serial one or vice versa.

You need to manage different signal lines

Virtual serial ports created with Virtual COM Port Driver fully emulate and support all usual hardware signal lines (DTR/DSR, RTS/CTS, RING, ERROR, DCD, etc.) As in real null modem connection, DTR of the local port is connected to DSR and DCD of the remote port, and RTS of the local port is connected to CTS of the remote port. Actually, you can leave default pinout schemes or set custom pinout ones to fit your personal needs and refine your applications.

Features of Virtual Serial Port Driver PRO

Virtual Serial Port Driver PRO is a comprehensive and effective software tool that extends the features and functionality of Virtual Serial Port Driver. This virtual COM port software allows the creation of virtual COM port bundles with customizable parameters, offering a versatile solution that can be used in many diverse scenarios. Management of both physical and virtual serial ports can be accomplished with the user-friendly interface of Virtual Serial Port Driver PRO.

Splitting and Joining COM ports

Physical COM ports (COM1) can be split into multiple serial ports (COM2, COM3, COM4) by using Virtual Serial Port Driver PRO. When you create these virtual com port drivers, they appear to your system as copies of the original physical port. Another feature of this virtual com port emulator is the ability of multiple applications to share physical serial interfaces. This software tool lets you link a number of virtual serial interfaces to one physical port. Serial applications that connect to the physical port can now receive data simultaneously from all of the connected serial ports.

Creating bundle connections

Creating and managing complex bundles of COM ports is a feature that is unique to Virtual Serial Port Driver PRO. The implications of this functionality is your ability to transmit serial data to an unlimited number of virtual or real serial ports. COM ports receiving data on the ‘IN’ can redirect to all of the bundle’s ‘OUT’ side serial ports and this process can work in both directions.

Management of hardware control lines is improved by creation of a Main port for both the ‘IN’ and ‘OUT’ side of a bundle.

Switching ports automatically

A notable feature of Virtual Serial Port Driver PRO enables expanded functionality for applications that can only use a limited number of serial ports. This option uses a switcher to enable your application to employ a single virtual port to be connected to several physical ports. You can also assign the same name to all of your ports.

Now when your application requires a COM port connection, the switcher identifies an open serial port from the list of connected ports and offers it to the program. This allows your application to seamlessly interact with whichever ports are free while appearing to be connected to the same port.

Merging COM ports

One of this virtual com port software’s advanced features enables the addition of unlimited numbers of virtual serial ports to a single COM port bundle that has not been divided into ‘IN’ and OUT’ sides. Replication from the single port to all connected physical and virtual ports of the bundle allows any application or device to simultaneously exchange data with multiple other applications or devices.
