Virtual serial port

Virtual serial port kit for simple and powerful serial port simulation

Virtual serial port - is a software solution that allows you to create virtual serial ports and connect them to each other using software based virtual analog cables, or connect them to different serial applications and virtual devices through named pipes.

The ports that need to connect to the virtual null simulation link do not need to be located on the same computer, they can even be located anywhere in the world and connected through a network connection. We provide developer APIs for your system to facilitate easy integration.

This product simulates all hardware serial port functions, including baud rate, data bits, parity bits, stop bits, etc. It allows you to control data flow, simulate all signal lines (DTR, DSR, CTS, RTS, DCD, and RI), and customize pin layout. VSP simulation hardware and XON/XOFF flow control, TX queue overflow and even line noise.

This is a completely software based solution that does not require additional physical hardware to run. For over a decade, this program has been developed and continuously improved. It provides you with a clear and intuitive user interface, detailed documentation, and can be used without programming skills. Download this virtual serial port tool now and start simulating COM ports within seconds!

Virtual Serial Ports feature

1. Local serial bridge and loopback

The product allows you to create any number of virtual ports and connect them in pairs through virtual analog cables. For any serial application, virtual ports, virtual null analog links, and their behavior are identical to hardware ports and cables.

1. Network based remote serial port bridging

The product allows you to create virtual serial port pairs that connect to each other through LAN, WAN, or Internet connections. Virtual serial ports are created on different computers. The listening port is used as a connection point for a remote virtual serial bridge.

1. Serial port in series

You can create a virtual serial port and connect it to a named pipeline for communication with the guest OS serial port created by VM simulation software. When used with VMWare, VirtualBox, Microsoft Hyper-V, and other software, virtual serial ports are very convenient.

1. Custom virtual null simulator pin routing

For the most comprehensive simulation of empty analog cables, our virtual cables allow you to specify the connections between virtual socket pins. Use one of the standard wiring layouts or create custom wiring. The virtual cable pin layout supports local and remote bridging.

1. Developer API for simple integration

Rich application programming interfaces allow you to control applications from your code or script. Various virtual serial devices and their configurations can be controlled from different programming languages, including C++, C #, or JavaScript/TypeScript.

1. TX buffer overflow simulation

This absolutely unique virtual serial port feature allows you to simulate TX UART buffer overflow situations. TX data buffer overflow can simulate local and remote serial bridge communication, enabling you to develop reliable applications.

1. Line noise simulation

This advanced feature allows you to simulate serial link noise. It will help you develop reliable and data loss resistant serial communication solutions, implement error correction algorithms, and more. Noise simulation is applicable for both local and remote serial bridging.

1. Automatically restore ports and links

This product allows you to create permanent serial ports and links. Their configuration is reliable for storage. This product is fully compatible with Windows power management, so the original configuration of each project will automatically recover when shutting down, restarting, or hibernating.

1. User defined serial port name

This product allows users to change the serial port name as needed. You can specify a custom virtual COM port number. User defined device names will be displayed in Windows Device Manager, for example.

1. Multi language user interface

The product interface supports multiple languages. Localization will be automatically applied. The language tool is suitable for all users, and anyone can edit or create their own language pack.

Virtual Serial Ports usage scenarios

1. Simulate hardware serial port for development purposes

If you are developing the software part of a project for devices connected through hardware serial ports, you may encounter difficulties. Most modern computers do not come with pre installed serial ports. You need some kind of software replacement, a virtual serial port simulator, which will replace the hardware part and make development easier. This is the function of virtual serial port.

1. Reverse engineering of traditional serial port applications

If you need to reverse engineer an application that uses a hard coded port number, you cannot achieve it by connecting to that port. The Windows platform only allows a single application to access this port. Here, virtual serial ports can help you create virtual bridges that map communication data to different port numbers, allowing you to connect and send bytes on behalf of real COM port devices.

1. Create a solution based on client server virtual serial port

If you need to create a geographically distributed client server solution that works with virtual serial ports, it is impossible to achieve it using only operating system tools. When your virtual port is created on computers around the world, you must use a network. Our product will save you development time by allowing you to create a remote serial bridge over a network connection.

1. Test and debug applications without the need for physical ports

Most modern computers do not have pre installed hardware serial ports. Therefore, when you need to test or debug serial applications, it is highly likely that your computer does not have hardware ports available for serial communication. In this case, our product will help you quickly replace physical serial ports with virtual serial ports, and then complete the task by connecting a software based "response part".
