Virtual Serial Port Control - Virtual RS232 ActiveX

Create and manage virtual serial ports

With VSP ActiveX your application is able to create ports that will fully emulate real ones, so any application will communicate with virtual COM port the same way as serial device is communicating with real serial port.

Virtual Serial Port ActiveX has an extended and advanced set of control methods, events and properties that allows your application fully mange virtual serial ports. Thus, you are receiving absolute control over created virtual ports. Your application using VSP AX will be able to send data to virtual COM port and other applications will receive it as from a real RS232 port.

Common objectives and our solutions:

Obtain full support of events, methods, and properties

Virtual Serial Port ActiveX fully automates the work of created virtual serial ports. A special function can be defined to find out about any event that occurred with the port: ports` state has changed, or new data has been received or sent. The same way you can configure your application to be notified about any event that happened to the port in the process of communication with any Windows application - whether the port was opened or closed, flow control or control line status altered, signal lines wiring manipulated, baud rate changed, etc.

Gain full control over virtual serial ports

Virtual Serial Port ActiveX allows your application to create, delete, and fully control virtual serial ports. This endows you with the fullest control over created virtual serial ports. Virtual ports created by your application will fully emulate the properties and behavior of real hardware ones, like connection line break, baud rate, different signal lines state, default or custom pinout schemes, etc. From your application you can control data sent to virtual COM port by other applications and respond to them by sending your own data to virtual port, which will be received by other Windows applications as from a real one.

Set custom signal lines wiring

Virtual serial ports created with Virtual Serial Port ActiveX emulate and support all usual hardware signal lines (DTR/DSR, RTS/CTS, RING, ERROR, DCD, etc.). As in a real null modem connection, DTR of the local port will be connected to DSR and DCD of the remote port, and RTS of the local port will be connected to CTS of the remote port. Moreover, you can either leave default pinout schemes for your purposes or set custom pinout ones to achieve best results of your work.
