Such a connection is the best way to allow use of rare and expensive serial devices by different users simultaneously.
This facility allows creating a full-fledged client-server architecture, which provides multiple connections and data sharing possibilities between different applications. The COM port redirector then begins relaying the application data stream between the virtual COM port and the device server. When the application opens a virtual COM port, VSPD makes an IP network connection to the device server at the specified IP address and TCP/UDP port number that corresponds to the remote device on the server. Additionally, it allows the data flow to be controlled, emulating all signal lines (DTR / DSR / CTS / RTS / DCD / RI) and customizing pinout.Īpplications use a COM port redirector through created COM ports virtual, as configured by the user. VSPD is capable of emulating the entire functionality, including Baud rate, data bits, parity bits, stop bits, etc. VSPD, our COM port emulator is as good as a conventional COM port driver, the system will not even notice the difference between virtual COM port and a physical one.

Let us take it as an example to see how to create virtual COM port.ĬOM port emulation means that com port software will create virtual com ports and pair them via null modem cable. These days there are a lot of such applications out in the market, and among them particularly popular is Virtual Serial Port Driver (VSPD) by Eltima. The good news is that we can emulate COM ports with the help of a COM port emulator. Serial ports are still widely used for testing and debugging applications. Nowadays however very few computers have serial ports, and many don’t have any. Serial ports, being one of the most basic external connections to a computer, for a long time have been an integral part of computers.
