Virtual RS232 Port Driver
RS232 Communication Software

Virtual RS232 Port Driver creates virtual serial ports connected via null modem emulator. These virtual COM ports work in pairs: data sent by one application will be instantaneously received at another end of the pair by another application.

The ports created by this virtual RS232 communication software appear to your operating system or application as standard serial ports. In fact a virtual serial ports not only do not clutter your desk, but also work faster than real ones. The virtual RS232 driver based on virtual null-modem can be included in your own software providing a way to create and configure virtual com ports directly from your application (OEM license).
Thinking about integrating our functionality into your own industry-specific solution?
Eltima Port Virtualization Technology is just what you need. Thousands of successful companies worldwide have already experienced the undeniable benefits and advantages of powering their software and hardware products with our advanced technology.

Virtual Serial Port Driver advantages
Virtual Serial Port Driver

Any number of virtual COM ports

The number of virtual RS232 ports you can create with the help of RS232 communication software is almost unlimited; while your real serial ports remain free. Virtual ports can be given any name, existent serial ports’ names included. The system sees and recognizes virtual ports as they are displayed in ‘ports’ group in Device Manager. You can set up a port so only particular applications will have access to it.

Real ports settings emulation

The system will not see any difference between virtual and real ports. Virtual com ports are as good as the real ones, they emulate all functionality, including Baud rate, data bits, parity bits, stop bits, etc. Virtual RS232 port driver emulates a serial line break and is fully compatible with API COM. VPSD uses advanced Windows kernel driver technology that allows WDM, WMI, Power Management, PnP, Windows messages, etc. support.

All signal lines support

Virtual RS232 null modem cable allows emulating and supporting all standard hardware signal lines (DTR/DSR, RTS/CTS, RING, ERROR, DCD, etc.). Just like a real one, virtual null modem cable connects DTR of the local port to DSR and DCD of the remote port, RTS of the local port to CTS of the remote port. You are free to choose loopback pinout or customize it to suit your hardware configuration best.
Virtual RS-232 Port Driver PRO features
Virtual Serial Port Driver PRO is an effective, all-inclusive software solution built on the functionality of Virtual Serial Port Driver. Creating bundles of virtual RS232 ports and setting custom port parameters is facilitated by this application, making it a great choice for use in many scenarios. Easily and conveniently manage real and virtual RS232 ports with Virtual Serial Port Driver PRO.
Virtual Serial Port Driver PRO
  • Splitting Serial Ports

    Virtual Serial Port Driver PRO enables the splitting of physical serial ports (e.g. COM 1) into multiple virtual COM ports (COM2, COM3, COM4, etc.). These virtual ports are presented to your system as exact copies of a physical serial interface. In addition, this RS232 communication software allows the sharing of physical hardware ports by multiple applications. This function allows a single COM port and its connected device to be accessed by several serial applications.
  • Joining COM ports

    Virtual Serial Port Driver PRO lets you create multiple virtual RS232 ports and link them to one physical serial port. Connected in this way, a serial application accessing the physical port receives data simultaneously from all linked virtual COM ports. This advanced feature lets you redirect data to one application from several different devices.
  • Creating bundle connections

    An option available when using Virtual Serial Port Driver PRO allows the creation and management of complex serial port bundles. Serial data can then be transmitted both in and out by unlimited virtual and physical serial interfaces. For example, serial data received on the ‘IN’ side of a COM port can be redirected to all COM ports on the ‘OUT’ side of the bundle and vice versa.

    You can also easily manage hardware control lines by setting the Main Port for both the ‘IN’ and ‘OUT’ side of a bundle.
  • Automatic Port Switching

    In cases where an application can only use a limited number of ports, a special feature of Virtual Serial Port Driver PRO called Switcher can be extremely beneficial. Using Switcher allows you to connect multiple physical ports into one virtual interface, or use the same name for all ports. Then you simply create a switcher in your app to make use of this specially created virtual RS232 port.

    When your program searches for a connection to a serial port, the switcher detects open COM ports from the list of connected ports and makes one available to the application. In this manner, your program will talk to any free serial connection automatically as if it were always the same port.
  • Merging COM ports

    Another advanced feature of Virtual Serial Port Driver PRO allows the addition of unlimited virtual and physical COM ports to a serial port bundle that has not been divided into ‘IN and OUT’ sides. Using this feature, all devices and applications have the ability to transmit data with all other devices and applications at the same time. All data sent to one port is replicated to all other ports in the bundle, both virtual and physical.
