You need to access a peripheral device located a considerable distance from your computer. Here’s a scenario where you could use Serial to Ethernet Connector to establish communication. The beauty of using virtual serial connectivity is that users gain the same level of functionality as if they were locally attached to the devices. They are also useful when dealing with serially-based point-of-sale equipment that needs to be accessed from a remote location. Industrial automation systems and production lines achieve tremendous benefits by routing their RS232 data transmission over network. Virtual Serial port over Ethernet - software Simply emulate them with as many virtual serial ports as you need. You can go ahead and buy that screamingly fast new laptop without worrying about the number of serial ports it does or does not have. So using virtual COM ports is a way to protect your investment in legacy serial-based equipment and applications. They do not have the ability to adapt to the modified data flow from a USB port. Without rewriting the code, many legacy programs will cease to operate without serial connectivity. It’s not as simple as using a different physical interface on a peripheral device. This can pose a serious problem if you use legacy applications that require serial interfaces with which to communicate. If your computer does have serial connectivity, the number of ports will be extremely limited. The majority of modern computers have neglected serial ports in favor of the more universally used USB interface. The main reason that virtual serial ports over Ethernet are useful is due to the limitations forced upon users by modern computer manufacturers. Data is converted in both directions to allow network transmission and then turned back to serial signals for interaction with devices and programs. A virtual serial port over Ethernet provides all of the functionality of a physical COM interface. When using a serial port emulator, data generated from a serial application or device is converted from serial data to information that can be transferred over an IP-based network. Virtual serial port over Network technology.Virtual serial port over Ethernet on Linux - full guide.Virtual serial port over Ethernet - Windows software tutorial.A virtual serial port can be used to send and receive serial data over a network such as a LAN or the Internet. These machines may not have any serial ports or might not have the necessary number available for a specific use. Virtual COM ports are used to extend the capabilities of computers and laptops that need to interact with serial devices but which lack physical serial interfaces.
