Communication method and device for application program and serial port peripheral

Abstract

The invention provides a communication method and device adopting an application program and a serial port peripheral. The method comprises the steps that a driving program receives the application data sent by the application program, wherein the application data carries identification information for identifying a target serial port peripheral; the driving program determines the target serial port peripheral based on the identification information and de-encapsulates the application data; the driving program encapsulates the de-encapsulated application data as serial port data, and the serial port data is sent to the target serial port peripheral. In the method, when the serial port peripheral is changed, only the driving program is needed to be perform synchronous change, the application program is not needed to perform synchronous change, and accordingly the problem that when a certain serial port peripheral is changed in the relevant art, all application programs in communication with the serial port peripheral are needed to execute synchronous change, accordingly the system stability is poor and the configuration burden of related personnel is increased can be effectively solved.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a communication method and device for an application program and a serial port peripheral. Background technique [0002] As a free and stable operating system, the Linux operating system is widely used in various electronic products, and serial port communication, as a basic communication method, is also widely used in the communication between serial port peripherals and CPU. [0003] In related technologies, in the process of communicating with the serial port peripherals, the application program configured by the Linux operating system needs the Linux operating system to first load the serial port driver architecture, and then the application program executes opening the serial port, setting attributes, reading and writing the serial port, closing the serial port, etc. A series of actions to realize communication with serial port peripherals. [0004] Although the relat...
