Back in the old days, serial ports served for connecting a computer with printers and external modems and nowadays the interface helps to establish a communication between scientific instruments, industrial applications, shop till systems, etc. Luckily, there are some dedicated hardware and software solutions designed to help you overcome all the abovementioned inconveniences.Ī serial port is one of traditional I/O interfaces used by a computer to exchange data with another PC or a serial-based device one bit at a time. This not only leads to cable clutter hanging down from the back of your desk but also makes it difficult to attach the device to more than one PC. Therefore, your PC should fit as many COM interfaces as many devices you want to connect to. Besides that, connecting every new peripheral to a computer requires a separate cable to be run to a separate serial port of the machine. This method of linking devices is not always convenient given the distance limitations of the hardware cable. On the other side, a typical RS232 connection is established via a regular cable that enables point-to-point communication. Considering the ubiquity and flexibility of the interface, the need for this efficient solution is expected to continue well into the future. It serves as a basic way of communication for hundreds of serial apps. Being a cost-efficient and reliable solution, this port is used by a great number of current hardware and software products. This way of communication is typical for today’s POS hardware (barcode scanners, receipt printers, payment terminals), automated industrial lines, specialized laboratory equipment (electrochemistry meters, spectrometers, spectrophotometers) and many other universal devices and instruments.įor many years RS232 has remained a standard protocol for the data transmission. A vast variety of modern day equipment is designed to connect to a PC with the help of a standard RS232 cable.
