Serial to Ethernet Connector (formerly VSPD.net) is the software-based solution that allows you to share up to 255 serial port devices over TCP/IP network turning your computer into low-cost terminal server. As the result, any serial port device connected to COM port could be accessed from anywhere in the world as if it is attached to local PC.
Serial to Ethernet Connector uses virtual serial port technology which fully emulates real serial ports and duplicates all their functionality. Windows OS treats virtual serial ports in the same way as real ones therefore you are no longer limited to just 2 real ports (less/any number of physical ports you have) per system and may create COM port connections without occupying any real serial port. To create such connection you should create serial port's connection pairs on two computers. You will specify IP address and port number to access to (in case you are setting up the client), port number and TCP/COM options to listen to (in case you are establishing the terminal servers) or remote serial port name to access (if you are emulating null-modem connection). These settings will be used to connect to remote computer. When serial port device, attached to real COM port, sends communication data it will be actually transmitted over TCP/IP network.
