Serial port communication device

The invention provides a serial port communication device, which comprises a serial port module in communication connection with target equipment; the receiving channel is in communication connection with the serial port module, and the receiving channel collects the data received by the serial port module by adopting an asynchronous cache queue and displays the data; and the sending path is in communication connection with the serial port module and the receiving path, and the sending path is used for receiving a user instruction, sending a control instruction for controlling the target equipment to the serial port module and updating the state of the control instruction in response to an updating instruction of the receiving path. According to the serial port communication device provided by the invention, the receiving path and the sending path of the serial port can be decoupled, and the problem of serial port data congestion is effectively solved. 本发明提供一种串口通信装置，包括：串口模块，与目标设备通信连接；接收通路，与所述串口模块通信连接，所述接收通路采用
