Abstract

The application discloses a communication method and system. Wherein, the method includes: determining multiple data channels between the barcode reader and the host, wherein the multiple data channels occupy the same physical channel, and the multiple data channels at least include a keyboard wedge KBW channel and a human-computer interaction device HID channel ; When the data to be transmitted is detected, at least one of the multiple data channels is used to perform data interaction between the barcode reader and the host. The application solves the technical problems in the related art that when the barcode reader interacts with different types of data with the host computer, it needs to scan the relevant graphic code, the operation is cumbersome, and the work efficiency of the barcode reader is low.

Description

technical field [0001] The present application relates to the technical field of communication, and in particular, to a communication method and system. Background technique [0002] The physical interface of the barcode reader currently on the market is PS / 2 (Personal System / 2, personal system / 2), COM port (Cluster Communication Port, serial communication port), USB (Universal Serial Bus, universal serial port bus) In other forms, when the barcode reader needs to set up the barcode reader or receive other HID data from the host during the working process, it needs to scan the relevant graphic code and send the graphic code to the host. After the host obtains the graphic code sent by the barcode reader, it sends a control instruction, wherein the control instruction can be virtual resource information or an instruction to configure the barcode reader. Among them, the sound level of the barcode reader and the status of the indicator light can be set. After the barcode reade...
