VSPD (Virtual Serial Port Driver) is a virtual serial port utility software developed by Electronic Team and other companies. It allows the creation of virtual serial ports that fully emulate the behavior and parameters of the hardware COM interface. Using this software, you can create as many virtual serial ports as you need. This means that the same serial device (printer, scanner, GPS device, etc.) can be easily accessed from multiple serial applications at the same time.
Virtual Serial Port Pair Creation: VSPD can create multiple virtual COM port pairs. Each pair is connected to the other so that any data sent to one port is automatically received by the other.
Flexible Configuration Options: Users can customize the parameters of each virtual serial port, such as baud rate, data bits, parity method, etc., to suit different software requirements.
Strong compatibility: VSPD supports almost all Windows systems, including versions from Windows 7 to Windows 11, and is compatible with multi-core processors and virtual machine environments.
Steps to Install and Configure VSPD
1 Downloading and Installing VSPD
Downloading VSPD Software: First of all, users need to download the latest version of the installer from VSPD’s official website.
Run the installer: After the download is complete, double-click the installer file and follow the prompts to install. The installation process is easy and does not require a restart of the computer.
Register and Activate: If you have purchased the Professional Edition, you need to activate the software by entering the activation code after installation to unlock all the functions.
2 Create a virtual serial port pair
Start VSPD software: After installation, open VSPD software and enter the main interface.
Create Virtual Port Pair: Click “Add Pair” button to create a pair of virtual serial ports. Users can customize the name of the ports, such as COM3 and COM4.
Configure Port Parameters: In the Port Settings page, you can set the Baud Rate, Data Bits, Stop Bits, and Parity.
Make sure these parameters are consistent with the software that needs to communicate to ensure the stability of data transmission.
Save the configuration: Click “Save” or “Apply” button to save the settings, so that the created virtual serial port pair can be seen in the device manager.
3 Test the virtual serial port communication
Select virtual port: Open the application that needs to use virtual serial port, and select the virtual COM port just created as the communication port in the program.
Send and receive data: Start data transmission, use the debugging function in the software to send data to COM3 port, and check whether the data can be received on COM4 to verify whether the virtual port pair is working properly.
Monitor data flow: In the VSPD interface, you can view the status of data transmission and use the built-in monitoring function to capture and analyze the transmitted packets.
Common Application Scenarios of VSPD
1 Software Development and Debugging
When developing software that requires the use of serial port communication, using VSPD can simulate a real hardware serial port environment to help developers test and debug data communication. For example, developers can simulate data transmission between multiple devices to verify the stability and compatibility of the program.
2 Industrial Automation and Remote Device Management
In industrial automation, VSPD can help users realize virtual communication between PLCs (programmable logic controllers) and monitoring systems. By creating virtual serial ports, users can test new data acquisition or equipment control strategies without changing the original equipment.
3 Remote serial port data transmission
VSPD also supports mapping virtual serial ports to remote devices on the network, enabling users to interact with remote serial devices via virtual serial ports. This feature is very useful in the Internet of Things (IoT) and remote control systems to reduce the limitations of on-site device connections.
