com port splitter - split serial com port

Split real serial ports among several applications

Serial Splitter lets you split and join serial ports, redirect the data from one port to another, and create complex port bundles. You can easily split one real port into many virtual ports in such way that multiple applications can get the same data from one port at the same moment. Serial Splitter works perfectly with real COM ports as well as with virtual ones.

Serial Splitter has also recently added yet another essential feature to its baggage - switcher. It can automatically determine the free port on the list of available COM ports and let the application to work with it. Moreover new Serial Splitter can log all events, which makes it easy to see which application opened the port and what parameters were used.

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.

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.

switch com ports

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.
