Virtual Serial Port Control is an ActiveX control which makes it possible to create virtual serial ports and fully control them. At the same time virtual ports look like they were real hardware serial ports for communications applications.

It is considered that communications applications are intended to work only with hardware serial devices connected to physical serial ports.

If there is a task to provide interaction between communications application and your own program (e.g. hardware device emulator), there is no common solution to accomplish it.

Features:

Virtual serial ports look and work like real COM ports.
Unlimited number of virtual COM ports can be created.
Virtual serial ports can have the same names as existing hardware COM ports (e.g. COM1).
Powerful and intuitive interface to make serial port communications easy.
Delivers all the capabilities of the Win32 Serial Communications API.
Notifies your application when data arrives or events occur on the port.
Supports reading and writing of binary data.
Full buffered data transfer.
Comes with example applications (Visual Basic, Visual C++).
Can be redistributed as part of your application.
