Serial port data processing method and system

Abstract

The invention provides a serial port data processing method and system. The serial port data processing method comprises the following steps: arranging a first-in first-out output buffer zone between a serial port and output equipment; storing data output from the serial port into the first-in first-out output buffer zone; and according to a set output speed, outputting the data obtained from the first-in first-out output buffer zone into the output equipment. The serial port data processing system comprises an output cache setting module and an output cache control module, wherein the output cache setting module is used for arranging the first-in first-out output buffer zone between the serial port and the output equipment, and the first-in first-out output buffer zone is used for storing the data output from the serial port; and the output cache control module is used for outputting the data obtained from the first-in first-out output buffer zone to the output equipment according to the set output speed. The technical scheme of the invention can quicken or slow down a serial port data speed received by the output equipment according to the requirements of testing personnel, and meanwhile, the keyword filtering of serial port data is supported.

Description

technical field [0001] The invention relates to a communication technology, in particular to a serial port data processing method and system. Background technique [0002] The serial interface is referred to as serial port for short, also known as serial communication interface or serial communication interface (commonly referred to as COM interface), which is an extended interface using serial communication. Its characteristic is that the communication line is simple, as long as a pair of transmission lines can realize two-way communication, thus greatly reducing the cost, it is especially suitable for long-distance communication, but the transmission speed is relatively slow. Because the serial port is easy to use and low in cost, it is now widely used in product development and testing. At present, there are many serial port communication software, such as SecureCRT, Xshell, etc., and these tools can be used to process serial port data conveniently. However, there are s...
