Eltima Port Virtualization Technology

Common objectives and our solutions

One-to-many ports connection (split RS232 serial port)

Serial Splitter splits one RS232 port (real or virtual) into several ones, which are precise copies of the original port in the system. Serial Splitter will give you the possibility to split real COM1 into virtual COM2, COM3, COM4 ports. To create a pure virtual ports pair you might also try Virtual Serial Port Driver.

Many-to-many ports connection (complex bundling)

Serial Splitter gives you the possibility to manage complex bundles of COM ports. You will be able to set up connection between a number of real, virtual or both kinds of serial ports in either incoming or outgoing direction.

Many-to-one ports connection (join serial ports)

Eltima Serial Splitter can help you join a great number of RS232 COM ports into one serial port. Thus, a single application connected to the port at the OUT side of the bundle receives information from several devices.

Share serial port among applications

If you have a device, connected to one real port on your PC, that you want to send data to and receive data from several applications at one time, you can share COM port with this device (or maybe some station) among multiple programs.

Create ports switcher

Switcher makes working with an application that can work with limited quantity of ports easy. You simply have to specify the name of one virtual port in the application and create a switcher for it in Serial Splitter. As many available ports can be added to the swicher as you need and joined under one name, so that it will be easy for any application to connect to the port that is free at the moment without changing the port name in settings.
