Virtual Serial Port Driver PRO is a highly-functional software solution that assists you in creating virtual COM interfaces and helps link serial ports to pairs in order to establish fast and reliable connections via a virtual null-modem channel. This professional utility allows you to customize port parameters as well as unite, split and merge hardware and virtual serial ports according to your requirements.

Here’s when Virtual Serial Port Driver PRO comes to the rescue

VSPD PRO gives you the way to create, edit, and delete an unlimited number of advanced serial port bundles with nothing more than a couple of clicks. Each bundle can contain as many physical or virtual serial ports you need.

Your computer lacks physical serial ports

If there are not enough hardware COM ports in your PC, Virtual Serial Port Driver PRO will emulate physical port parameters and configuration and create virtual serial interfaces that will work with your serial programs and devices like physical communications ports.

You need to split one port to make it accessible to many apps at a time

If you want several applications to receive data from one hardware serial port simultaneously, you can split this port into several virtual interfaces using the dedicated software tool. By connecting to a virtual copy of the hardware port, each of the utilities will be able to access the same hardware port and a device inserted into it.

You need to join any number of physical communications ports

When you combine several physical COM ports into one virtual, it allows enabling the simultaneous communication between several serial devices and a single application. The software gives the way to redirect data from every joined physical port to a virtual serial interface.

You are looking for a way to share GPS data among multiple programs

What sets the software PRO edition apart from most similar solutions is the ability to reroute serial data flows within complex bundles of serial interfaces. You add the desired number of COM ports to the IN and OUT sides of your bundle, and multiple communications programs get the chance to transmit the received GPS signals to other serial apps.

You want to automatically access a free COM port

VSPD PRO offers the port switcher option which makes it possible to automatically provide your application with access to a COM port being currently unoccupied. To do this, you simply link several hardware ports to a virtual one and make sure your program is connected to this interface.

It's required to enable many-to-many port connection

Merging unlimited number of ports within one bundle is one of the newest features delivered by Virtual Serial Port Driver PRO. There are no IN and OUT sides, all ports (and, thus, programs and devices) can talk to all ports at the same time.

What customers say

Simon Davison, Engineering Lecturer, Ham Radio

Serial Port Splitter (Virtual Serial Port Driver PRO) helps Ham Radio members who have multiple transceivers, satellite antenna controllers, regular antenna rotators and run data modes and packages like Ham radio deluxe, TRX Manager, WX to IMG etc. For myself, I have been playing around trying to configure a couple of apps that run my YAESU FT-847 and West Mountain RIGblaster plus.

Dave Belville - Straight Key Century Club QSOP Manager

Using Eltima Virtual Serial Port Driver Pro and splitting COM1 into five individual virtual COM ports, I am able to have four logging programs and one radio control program all connected at once using the “Split Port” feature. And, since all programs and devices are not created equal, Eltima Virtual Serial Port Driver Pro allows you to change and customize the individual virtual COM port settings to work with your application. I have not had any problems, reliability issues or failures. The software just plain works and works well. I highly recommend Eltima Virtual Serial Port Driver Pro to anyone that struggles with serial port shortages. You can create as many virtual serial ports as you need. The software is efficient, powerful and reliable. I wish I had found it sooner.

WV3P, Ham Member

After a lot of internet searching, I came upon a program Virtual Serial Port Driver PRO that allows me to setup virtual serial ports. I tried some other companies, and maybe someone has a better mousetrap, but this program works, and works well. I'm now running WSJT-X, and N3FJP at the same time, and everything tracks beautifully! The catch? It's an expensive solution, but for the serious contestor this may offer an answer. Hams are a notoriously "frugal?" bunch, and maybe someone else has a better solution. All I can say is this program is simple to setup, and works well. I had it setup and running in 10 minutes. You're mileage may vary.

James Smith, CNC metalworking industry

We needed a way to communicate seamlessly with existing serial-based third-party systems without adversely impacting the communications of the existing system. We chose VSPD PRO because of the capability of the product and the wide array of additional products. We are aimed for long-term cooperation and wanted to work with a stable, dynamic company and not be tied to a small company with an uncertain future. Serial Port Splitter works as promoted, it’s stable and we have no problems with it.
