This software allows creation of virtual COM ports directly from your own programs and provides full control. It enables interaction between serial communication applications and your program. The OEM license also allows distribution of this ActiveX control as a part of your software.

However, Virtual Serial Port Control makes it possible to create virtual serial ports directly from your program and have full control over them. The virtual ports are designed to look like real hardware serial ports, which means that any Windows application can work with them just as they would with physical ports.
The developer API provided in Virtual Serial Port Control enables your program to access data that has been written to the virtual serial port by communications application and to respond with your own data. This way, the data will be read by communications application from virtual serial port as if they were read from a physical port. Additionally, the event driven architecture in Virtual Serial Port Control is a snap to use. You don't need to check ports constantly to determine whether their state has changed, or if new data is available for reading from a port. By simply defining a function in your program that will be triggered automatically by the appropriate event, you can process the data effectively.
With Virtual Serial Port Control, you will enjoy full control over the virtual serial port. Anything that can be done with a physical serial port by a serial device is possible with the virtual serial port provided by VSPC. Furthermore, the OEM license enables you to distribute this ActiveX control as a part of your own application, without having to license every single copy.
In summary, Virtual Serial Port Control is a powerful tool that offers a solution to the challenge of providing interaction between communications applications and your own program. By creating virtual serial ports that function like real hardware serial ports, it makes it possible for any Windows application to work with them as if they were physical ports. Additionally, you can enjoy full control over the virtual serial port and distribute the software as part of your application, without having to license every single copy.
