With Serial Splitter you can create:
One-to-many ports connection
With Serial Splitter you can split one COM port into several virtual ones, which are exact copies of the original port in the system. For instance, Serial Splitter can split real COM1 into virtual COM2, COM3, COM4 ports.
Alternatively you can share one real port with device connected to it (i.e. GPS-receiver) among many applications without splitting it to several different virtual COM ports.
Many-to-one ports connection
Serial Splitter can join any number of COM ports into one virtual serial port, thus allowing information from several devices to be received by a single application connected to the port at the OUT side of the bundle
Many-to-many ports connection
Serial Splitter and its easy-to-understand assisting charts let you arrange complex bundles of COM-ports. You will be able to establish a connection between any number of real and virtual serial ports in either incoming or outgoing direction. Besides serial port data transmission, Serial Splitter provides the option to set Main Port for each side (IN/OUT) to manage control lines of a corresponding serial port.
With switcher you can enhance the work with those application that can work with a limited quantity of ports only. Simply specify one virtual port in such application and create a switcher for this port in Serial Splitter, where add all COM ports you'll need (and you can assign the same name to all of them for more convenient usage). So the program works with any free port Serial Splitter assigns to it as if it were always the same port.
