Virtual Serial Port Driver

Virtual Serial Port Driver is a useful tool for people who test and develop serial port software. It also works well for debugging. If you need more COM interfaces than your computer has, this product creates as many virtual ports as you need. Even if you don't have any real serial ports on your computer, Virtual Serial Port Driver for Windows will work for you. Through a virtual null-modem connection, the driver gives you pairs of virtual serial interfaces that communicate with each other. Virtual Serial Port Driver is used as a standalone application, and developers can integrate the same technology into their own products through the Virtual Serial Port Driver SDK. By upgrading to the Pro version, you can also split and join serial port data streams, merge real and virtual ports into bundles, or create a port switcher that connects your application to whichever device is currently free.

Another benefit of this product is that it doesn't require any additional hardware or cables for installation and usage.

None of your actual COM ports need to be tied up. The virtual ports emulate real ports as closely as possible and appear in Device Manager as though they were physical interfaces, so the applications you use will not notice the difference. Data travels from port to port instantly, and strict baud rate emulation lets the virtual connection match the speed settings of your device or application. The driver supports all standard hardware signal lines (DTR/DSR/CTS/RTS/DCD/RI) and HandFlow control (hardware and Xon/Xoff), and it can emulate a serial line break. The driver removes virtual ports just as easily as it creates them. The product is commercial software with a 14-day fully functional trial, developed by Electronic Team, Inc., the company formerly known as Eltima Software.

It lets two serial communication applications exchange data through virtual COM ports without real serial hardware or cables.

One benefit specific to the Pro version of this product is that it allows you to merge any number of real and virtual COM ports into a single bundle. Such a bundle is not divided into the typical two sides, "IN" and "OUT", as with a simple pair of ports. Instead, anything written to an individual port is replicated and transmitted to all other ports of the bundle, both real and virtual. You can exchange data with multiple devices and apps at the same time, and the Pro version also offers Split, Join, Switch, Redirect, Share and Loopback bundles for more complex serial setups.
