The Application of the Computer's Serial Communication port

Serial communications as one of computer communications ways,primarily as the host and peripheral data transfer between the host and the role of serial communication with a transmission line of small,low cost features,mainly for short range of people-machine exchange,real-time monitoring system communication work,by existing telephone network long-distance transmission can be achieved,so the serial communication interface is common among computer systems interface.This paper Based on describes the serial communications in the profile,introduction of serial communication port development and application of technology.
