Create custom virtual serial ports

Virtual Serial Port ActiveX Control is a powerful component by Eltima Software, that allows your application to create custom additional virtual serial ports and fully control them. Created virtual ports look and behave exactly like real serial ones, and not a single Windows application will recognize the difference.

You will be able to control all data sent by your application to other applications and respond to them by sending your own data. With Virtual Serial Port ActiveX Control your application will be able to communicate with virtual RS232 COM port the same way as serial device is communicating with real serial port.

Virtual Serial Port AX Control is completely compatible with Windows 7 and with 64-bit platforms too!

With Virtual Serial Port ActiveX you can:

Gain full control of virtual serial ports

If you embed Virtual Serial Port ActiveX Control into your project, your application will be able to create, delete and fully control virtual serial ports. This feature provides you with full control over the created virtual com ports and port pairs. Virtual COM ports fully emulate the properties and behavior of real hardware ports, including connection line break, baudrate, different signal lines, default or custom pinout, 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 like from a real one.

Set custom signal lines wiring

Virtual RS232 ports created with Virtual Serial Port ActiveX Control emulate and support all usual hardware signal lines (DTR/DSR, RTS/CTS, RING, ERROR, DCD, etc.) As in real null-modem connection, DTR of the local port is connected to DSR and DCD of the remote port, and RTS of the local port is connected to CTS of the remote port. More than that, you can choose loopback pinout or create custom one depending on your hardware configuration, or leave default null-modem scheme to fit all your technical requirements.
