Pro version of Virtual Serial Port Driver

For those of you who are looking for a simple way to create not only virtual COM port pairs but also their bundles with various custom parameters, the app developers offer the Virtual Serial Port Driver PRO version. This edition is tailored for professional use by serial port software and hardware developers and testers.

The utility comes with a range of advanced features like:

  • Splitting and joining serial data streams.

You can easily split a single real RS232 port into multiple virtual COM ones that will fully emulate the physical port. Also, you’ll be able to join multiple real port data streams into virtual one which will be directed to the required app or device.

  • Creating bundles of real and virtual COM ports.

Virtual Serial Port Driver Pro makes it possible to create complex port bundles where multiple virtual and real serial ports can exchange the incoming data with all the other ports added to the bundle at a time.

  • Automatic port switcher

Anytime your application needs to connect to a serial port, the switcher option will link it to a COM port being currently free. For this, you just create a bundle of virtual COM ports that will emulate a single real one. By communicating with one of the virtual ports, your app will, in fact, talk every time to the same real interface.
