Software design method for dial-up networking of network billing terminal

Abstract

The invention discloses a software design method for dial-up networking of a network billing terminal. The software design method for the dial-up networking of the network billing terminal is a software design method for the dial-up networking of a special embedded type billing terminal based on embedded type Linux operating system in tax industry. The software design method for the dial-up networking of the network billing terminal is mainly used for the drive-free design and general support of general networking card equipment with a USB port in the embedded type Linux operating system. The software design method for the dial-up networking of the network billing terminal is capable of effectively meeting the need of the network billing terminal for networking through the universal networking equipment with the USB port through equipment description information extraction technology, USB-to-serial line technology, PPP dialing technology and the like when the USB port equipment is electrified, and the networking equipment can be used at once after being inserted without distinguishing the type of the networking equipment; the software design method for the dial-up networking of the network billing terminal effectively solves the universality design of a network billing terminal software and prolongs the life cycle of the network billing terminal software.

Description

Technical field [0001] The invention relates to the field of network technology, in particular to a method for designing dial-up Internet access software for a network invoicing terminal. The dial-up Internet software design method designed by the patent of the present invention is applied to the dedicated network invoicing terminal based on embedded Linux in the tax industry to meet the different network access requirements of taxpayers, so that the network access of the network invoicing terminal is not limited to geographic location , Network wiring, USB interface network equipment product model restrictions. Background technique [0002] The existing network invoicing terminal realizes the Internet through the USB interface network device, which needs to be customized according to different types of equipment. The equipment is a general-purpose product. The replacement cycle is short, which causes the network invoicing terminal to frequently change the software to meet Diffe...

AI Technical Summary

Problems solved by technology

[0002] The existing network billing terminal realizes the Internet access through the network device of the USB interface, and needs to carry out customized driver development according to different types of devices, and the device is a general-purpose product with a short update cycle, which leads to frequent software changes for the network billing terminal. Different models of network equipment

The shortened life cycle of the software directly leads to the increase of software development and testing costs, resulting in unnecessary investment in human resources, and also increases the maintenance cost of the network billing terminal. Therefore, a technical means is needed to solve this problem and meet the needs of network billing. The terminal generally supports different types of Internet devices to meet the user's network access needs
