Electronic devices such as barcode scanners, surveillance cameras and various lab instruments typically use RS232 serial cable connection to interact with a computer. Most computers are equipped with at least one RS232 serial port, and getting a serial adapter for it is never a problem.
RS232 serial communication protocol has a reputation of being flexible and it is well established. With the large number of affordable hardware and software solutions that have been developed for it, RS232 protocol is here to stay, and will most probably remain the most popular interface for industrial electronic equipment for quite some time.

Serial over network sharing options
Serial port communication typically requires a hard-wired, point-to-point cable connection, and it is limited by the length of the cable, i.e. it can only run as far as your cable allows you to. If you want to connect multiple serial devices to one computer, you will need a separate cable and available RS232 serial port to communicate to each of them. Apart from cable clutter, it will be almost impossible to make a device to talk to more than one PC.
Luckily there are serial over network hardware and software that enables you access numerous serial device over any distance. Let us see how it works.
