Introduction to Virtual Serial Port Driver

Today, COM ports are still in use in many areas, including industrial automation systems, laboratory automation or surveying, POS systems, and more. And if your system lacks serial interfaces, it may become rather challenging to work with COM-based equipment or software.

Virtual Serial Port Driver (VSPD) is a professional utility that allows creating virtual serial ports which completely emulate the behavior and parameters of hardware COM interfaces. With the software, you can create as many virtual serial ports as you need. That means you’ll be able to easily access the same serial device (printer, scanner, GPS device, etc.) from multiple serial apps at a time.

Virtual Serial Port Driver provides the great opportunity to set custom port parameters and create COM port bundles of different types. The software is an efficient solution for managing real and virtual serial ports:

The software makes it possible to provide your system with an unlimited number of virtual COM port pairs. Thanks to the advanced pairing option, you can exchange data between serial apps using a virtual pair connected with a virtual null modem cable.

Another great feature of Virtual Serial Port Driver is splitting one physical COM port into several virtual ones. In this case, all data received by the split real interface can be sent to each of the OUT-side virtual ports and vice versa.

With Virtual Serial Port Driver it’s also possible to join multiple physical COM ports into one virtual. That means everything sent to one of the joined real ports will be duplicated to the virtual serial port, and vice versa.

In case you need to create a bundle of real or virtual serial interfaces where all ports will be able to talk to each other, you can easily do this with the app’s port merging feature. Everything sent to one of the merged ports can be replicated to all the other ports of the bundle.

Virtual Serial Port Driver will also come in handy for redirecting serial traffic from one real COM port to another (real or virtual serial interface).

What’s more, the port switching option will let you add several real ports to one port bundle and join the bundle to a single virtual COM port. Once you create a switcher for this virtual serial port in your app, your program gets access to all real ports joined to the virtual one. Now, any time your app needs to connect to a COM port it will be automatically offered a free real interface. The app will connect to different physical interfaces as though it were always the same port.

When working with multiple applications at a time, you may need to share one COM port among several programs so that the apps can access the same serial port simultaneously. Virtual Serial Port Driver makes this possible. You simply connect all the apps you need (the number is not limited) to a single COM port with the software, and your programs get the ability to send and receive the port’s data at a time. In addition, you may grant access rights to a particular application and specify serial port connection parameters (baudrate, databits, etc).

To make your work even more efficient and productive, you can use the unique complex bundle feature that combines all those amazing options mentioned before. It lets you create multiple serial ports at both sides of a bundle, with data redirected from several incoming ports to several outgoing ports. Both sides of a bundle can have virtual serial ports, real serial ports and shared ports installed.
