![]() ![]() Nevertheless, serial COM ports are still often used in industrial settings to connect factory machinery, equipment, and devices to industrial computing solutions. So, alth ough it’s very reliable, it lacks the ability to transfer data quickly. For example, the RS-232 standard is capable of transferring data at a maximum of 1Mbps. ![]() That said, one of the biggest limitations of COM or serial ports is that their data transmission rate is extremely low. ![]() So, the myth that serial ports are obsolete simply isn’t true since they are still heavily used in industrial settings. Serial ports are extremely reliable, and this is proven by the fact that they are over 60 years old and still in use today. However, today, COM ports are typically only available on industrial computing solutions, connecting industrial computers with legacy factory equipment and machinery. Hardware components include mice, modems, and printers. In the past, Serial COM ports were used to connect hardware components to computers.

Most devices that still utilize serial ports utilize the 9-pin D B -9 connector and are usually referred to as COM ports, with COM being short for communication ports. Although modern PCs have eliminated the se ports ’ use, these ports are still commonly found in industrial setting s where simple connectivity is still in demand. Other related standards include RS-485 and RS-422. The most popular serial port is the RS-232 port, which came standard on many computers in the early sixties. They are used to sequentially send and receive data, sending and receiving one bit of data at a time. Serial port s are se rial communication interfaces that were introduced in the early sixties. We will provide you with everything you need to know about serial ports and USB ports, as well as how both communication ports are used in industrial settings. If you are curious to learn about the differences between serial ports and USB ports, you’ve come to the right place. ![]()
