With COM Port Splitter you can split one real port into several virtual ports, join real ports into one virtual, and redirect the serial traffic from real port to another real or virtual. You can also share one real serial port among several applications so that they will receive the same data from one serial port simultaneously. You can also join several ports under one name and let applications switch among the free ones. COM Port Splitter is very good at splitting any hardware COM port into multiple virtual COM ports, so that each of them behaves exactly like the original port and has the same name. All virtual ports receive any data that is received by the original port at the same time. For example, COM Port Splitter can let a single serial device interact with multiple applications at the same time. Another job COM Port Splitter can do for you is join some real COM ports into one virtual port, which is rather useful when you need some application to handle multiple serial devices simultaneously. All data received by one of the joined COM ports is instantly forwarded to the joining virtual port and to the application, and vice versa. It is also possible to redirect all serial traffic from a hardware COM port to another COM port (hardware or virtual) with COM Port Splitter, meaning that any data sent to the redirected port is immediately received on the port you redirected it to. You may need this in case you are using some software with very strict serial-port settings and instead of figuring out how to modify those settings you can just redirect the data traffic to it. Besides, COM Port Splitter is essential for creating complex bundles of real and virtual serial ports and interconnecting them as you wish, therefore enabling data exchange between those ports.

With Serial to Ethernet Connector you can share up to 255 serial devices over network turning your computer into a terminal server. With this serial over network solution any device connected to a COM port can be accessed and used from any spot on the globe as if it were physically connected to the local machine. The data sent by serial port device is transmitted over a TCP/IP network. This is achieved thanks to our virtual serial port technology that emulates standard COM ports behavior and Windows OS treats the virtual ports as the real ones. Although the ports are treated as physical you are not limited to the quantity of physical COM ports and can create COM port connections without occupying real serial ports. With Serial to Ethernet Connector you can: share serial port for incoming connections, connect the port to remote host, or share port using UDP connection. Starting from version 7.0 Serial to Ethernet Connector got absolutely new user interface for even easier creation and management of connections with latter conveniently visualized and more.

The main goal of Virtual Serial Port Driver by Eltima Software is creating virtual COM port pairs. Virtual serial ports created in VSPD behave as if they were real ports and are taken for the real ones with the serial applications. Via these ports serial applications can communicate with each other and transfer data via virtual null-modem cable. The data written to one virtual serial port can be instantly read from the other. Virtual serial ports created in VSPD support all serial port settings, strict baudrate emulation, HandFlow control and signal lines. After virtual COM port pair was created, one can see these ports in Device manager, moreover these ports are available automatically at system startup, even prior to logon. Virtual Serial Port Driver is available in a GUI version as well as a driver version with API for those who are going to use it in their own product.
