Embodiment Construction
[0023] The invention uses the peripheral configuration tool to command configuration of the peripheral, generates a configuration parameter file, and the host application calls the configuration parameter file, thereby driving the peripheral, avoiding the application program directly driving the peripheral, which is beneficial to the expansion of the system hardware and the application program The stability of the version.
[0024] The peripheral configuration tool is provided by ACE, a product of Digital China. ACE is a set of operating platform developed for the host system, which can realize the functions of human-computer interaction interface control, device driver, communication transmission machine database operation and so on required by the foreground system. See figure 2 It is a schematic diagram of a typical ACE application. The host can communicate with the terminal through the ACE server and client provided by ACE; it can also communicate with the terminal using a ...

The invention discloses a method for a host computer to drive a peripheral device, comprising the steps of: configuring a peripheral device instruction set, generating a configuration parameter file; receiving a peripheral device operation request, calling a configuration parameter file, and finding an operation instruction corresponding to the operation request; Sending a control statement with the instruction as a parameter, the peripheral includes a character mode peripheral and a graphic mode peripheral; the peripheral executes the instruction carried by the control statement. The host application drives the peripheral by calling the configuration parameter file, thus shielding the application from directly calling the peripheral, which is beneficial to the expansion of the peripheral; when driving a new peripheral, it only needs to generate a configuration parameter file through simple configuration Drive the peripherals, thereby protecting hardware resources and enhancing the scalability of the system. The invention also discloses a system for the host to drive the peripheral.
Description
Technical field [0001] The present invention relates to the field of computer technology, in particular to a method and system for a host to drive peripherals. Background technique [0002] In such figure 1 In the computer system shown, the host communicates with various peripherals through a network, and when a peripheral is to be operated, the peripheral is driven by the host application. Peripherals include various terminal devices such as notebook computers, printers, cameras and scanners. [0003] At present, the host drive peripherals are generally realized by reading and writing serial and parallel ports. In this way, the peripherals are directly driven by the host application program. For example, when a peripheral is to be "turned off", the host application will use the peripheral's "turn off command" as the parameter of the control statement, and send the control statement to the peripheral, and the peripheral will execute the control after receiving the control statemen...
