Broken line keeping method, device and equipment and computer storage medium

Abstract

The invention is applicable to the field of data information processing, and provides a disconnection keeping method, device and equipment and a computer storage medium, and is applied to a driving module in terminal equipment, the method comprises the following steps: when external equipment establishes physical connection with the terminal equipment, creating a first logic unit and a second logic unit in the driving module, the application software interacts application data with the external equipment through the first logic unit and the second logic unit in sequence; if the physical connection between the external device and the terminal device is disconnected, the second logic unit is deleted, and the first logic unit receives and caches application data sent by the application software; and if the external device recovers the physical connection with the terminal device, re-creating the second logic unit, and sending the application data cached by the first logic unit to the external device through the second logic unit. The problem of communication interruption caused by a misplug event of external equipment can be solved.

Description

technical field [0001] The present application relates to the field of data information processing, and in particular to a disconnection maintenance method, device, equipment and computer storage medium. Background technique [0002] The virtual serial port driver is a kind of driver program that we often come into contact with in the process of using the computer. There is no corresponding serial port hardware on the computer. Instead, a virtual serial port driver is used to virtualize several serial ports on the computer. The application software uses the application program interface corresponding to the virtual serial port to access the application platform. For example, when an external device (such as a USB flash drive) is connected through an interface on a main box of a personal computer (Personal Computer, PC), the program on the PC realizes the interaction between the PC and the external device through a virtual serial port driver. [0003] However, in practical a...
