Why is VSPD the Best Null-modem Emulator?
Virtual Serial Port Driver has numerous advantages over the most popular null-modem solutions:
- Out-of-the box solution for any Windows
Virtual Serial Port Driver can run on modern versions of Windows, up to 11, and legacy versions can be requested for systems running Windows XP or later. Windows Server and ARM are supported as well. The drivers have fully passed WHQL tests and were digitally signed by Microsoft.
Installation is simple, with no additional components required. The GUI does not rely on the .NET Framework.
- Convenient port management
Ports created by VSPD are active immediately, with no need to restart the system, and the same applies to all setting changes. They can be set to persist between sessions, freely renamed, and viewed in the Device Manager. A port connection can be disabled or removed at any time, and there is a port access list that allows you to permit or restrict applications from using them.
- Support and integration
Our null-modem technology can be integrated into your product with the help of a flexible SDK, and unlike many open-source licenses, will not require you to publish the source code. If you decide to try integration, our support team will be with you every step of the way. We will be happy to assist you with any potential issues you may have while using VSPD.
More on Virtual Serial Port Driver
We’ve designed Virtual Serial Port Driver to establish and manage null-modem connections between serial applications. This is done with the help of virtual ports that can easily be renamed and configured. An emulated port is much faster than a physical one, and you have the choice to either make use of that speed, or, if authenticity is important, to enable strict baud rate emulation.
Port settings include baud rate, parity, data and stop bits, as well as the type of handshake used for the connection. They can be restricted to input/output only, and a custom pinout can be specified, including loopback pins. Once a null-modem connection is created, you can use Virtual Serial Port Driver to check whether it’s active and see the amount of data that has been transferred between the ports.
VSPD is an essential COM port testing tool, and you can try it for free right now. A 14-day free trial is available with the basic features of the Standard license.
Virtual Serial Port Driver PRO
When you need to connect more than 2 devices, Virtual Serial Port Driver PRO is the best solution. It adds a large number of additional connection types to VSPD, to choose from and configure for any situation.
- Split physical ports to connect to multiple receivers, or join multiple ports
- Merge multiple ports and have every port in the bundle communicate with all others
- Create complex bundles, specifying the communication side for each port
- Have VSPD automatically choose free physical ports for your applications
- Create a loopback connection and redirect the port’s data into itself
