Create and control virtual COM ports through your own application.

Virtual Serial Port Control is a powerful software development kit (SDK) that allows you to create virtual serial ports and fully control them. It is very useful when creating a serial device simulator or when adding new logic to existing traditional serial communication applications.

Virtual serial ports appear in the operating system like regular hardware COM ports, so serial communication applications use them like real hardware serial ports.

On the other hand, programs that use developer APIs retrieve all data written to the virtual serial port through communication applications. Then, your application may respond with your own data, and the communication application will read this data from the virtual serial port in the same way as it reads from the physical port.

Software development toolkit

The virtual serial port API is presented in the following form:

1. Dynamic Link Library
2. ActiveX
3. . NET Components

The SDK comes with complete documentation, source code examples, and components, which can be integrated into third-party installation programs.

Event driven architecture

The event driven architecture is a soft snapshot. You don't need to regularly check the port to see if the signal has changed or if there is new data available for reading from the virtual serial port. Just define the required routine in the code, which will be automatically triggered by appropriate events and process data.

At the same time, the virtual serial port control will immediately notify your application about communication applications (port opening/closing, setting DTR/RTS handshake, baud rate setting, XON/XOFF setting, etc.).

Fully control the serial port

This API provides developers with complete control over virtual serial ports. Combining APIs with virtual serial ports can do as much as combining physical serial devices with real serial ports. The communication method between this solution and virtual serial ports is the same as the communication method between serial devices and physical serial ports.
