Serial Port Splitter software shares dataflow between multiple devices or apps through virtual serial port technology. This allows multiple COM port devices to combine dataflow for one app or share dataflow from one COM port across multiple apps.

One of the main features that make Serial Port Splitter stand out from other similar software applications is that one COM port can be splitted up to 254 virtual ports, allowing users to configure a large number of ports with ease. Moreover, it also allows several applications to open one COM port and multiple COM ports to join together to create a virtual port.
The program’s READ/WRITE or READ ONLY mode for splitted serial ports is extremely convenient and ensures that data flows smoothly between applications without any disruptions. Similarly, the WRITE ONLY or READ/WRITE mode for joined serial ports guarantees efficient data sharing between connected devices, making it an ideal tool for users who require constant data exchange.
Serial Port Splitter’s virtual serial ports operate at each system startup, and the software is compatible with various technologies like Hyper-Threading Technology, PnP, and WMI technologies, as well as VMware software. The user-friendly interface of the software ensures easy navigation and operation, providing a hassle-free user experience to its users.
The software also has a hot program install feature, which eliminates the need for system reboot, significantly reducing users' downtime while performing system updates. Overall, Serial Port Splitter is an outstanding tool that provides an efficient solution to users' serial port splitting and sharing needs. Its robust functionality and ease-of-use make it a must-have software application for those looking to optimize their data flow and communication between their devices.
