Abstract

The invention provides a serial port redirection method and system. The method comprises the following steps that: a. terminal serial port redirection is initialized; b. a virtual serial port controller intercepts the I / O (input / output) request and operation of a user on serial port equipment and redirects the I / O request and operation to a terminal; c. a terminal serial port controller processes the received redirected I / O request and operation and returns the processing results to the virtual serial port controller; and d. the virtual serial port controller analyzes and processes the processing results returned by the terminal and then returns the analysis and processing results to an operating system, and the operating system finally feeds the I / O processing result fed back by the virtual serial port controller back to a user experience layer. The method and the system have the following advantages: equipment use experience on the traditional desktop is provided; the compatibility is good; and flexibility and convenience are ensured.

Description

technical field [0001] The invention relates to the technical field of port redirection, in particular to a method and system for serial port redirection. Background technique [0002] The serial port provides a device-independent computer communication method, and supports a wide range of device types. Existing desktop virtualization protocols have built-in serial port channels to provide support for the use of serial port devices in desktop virtualization environments. As long as the serial port channel of the relevant desktop protocol is opened, the serial port device connected to the terminal can be freely used in the virtual desktop session. [0003] However, existing serial port devices suffer from the following problems: [0004] A. Device experience is different from traditional desktop [0005] The existing serial port technology does not create an end-to-end mapping from the serial port on the terminal to the virtual desktop by creating virtual devices and corre...
