Serial Port Switcher
RS232 Switcher - split and switch serial ports

Serial Port Switcher is a software solution that enables splitting a single serial port into multiple virtual ports thus allowing several apps to connect to it and receive data simultaneously. This serial switch app is also capable of connecting multiple ports into one, creating bundles and redirecting data from one port to another. The rs232 switch app basically allows you to manage real hardware, as well as virtual ports.

The serial port switch functionality allows detecting a free port – you have to specify a list of COM ports first – so it can be assigned to an application that requires it. In addition to switch serial ports, the app logs all events in the system, you thus can track what application communicated with the port and the connection parameters.

Serial Port Switcher allows creating the following connection types:

  • One-to-many

    This rs485 switch app allows splitting a serial port into multiple ports, each of them would copy all the parameters of the hardware port. It is also possible to share the device connected to a serial port among multiple apps without splitting the port into several.
  • Many-to-one

    The app can connect multiple serial ports into a single one. This might be required if you want a single application to receive data from several devices, the application should be at the OUT side of the bundle.
  • Many-to-many

    Setting up complex bundles of serial ports with the help of Serial Port Splitter becomes easy, thanks to assisting charts provided by the app. You can bundle any number of serial ports, virtual, as well as real, in any direction – incoming or outgoing. For IN/OUT sides you can set up the Main Port, this will enable you to manage control lines of a corresponding serial port.
  • Ports switcher

    Switch rs232 functionality simplifies working with applications that require only a certain number of ports for functioning. Assign a virtual port for such an app, i.e. specify it in the app; add a switcher to this port in the Serial Port Switcher and all serial ports you need to interact with. For your convenience you can give all of them the same name. Next time the app needs to connect to the port, the Serial Port Switcher will automatically detect a free port and assign it to the app.
