Embodiment Construction

[0009] see figure 1 As shown, the redirection system of the serial port data of the present invention includes several managed servers 10, and these managed servers 10 are used to receive UDP (User Data Protocol, User Datagram Protocol) data packets respectively, and the received UDP data packets will be The management server 10 converts the received serial port data into received serial port data, and then obtains corresponding returned serial port data according to the received serial port data, and the returned serial port data will be converted into returned UDP data packets in the managed server 10 and output. These managed servers 10 are respectively connected to a management server 20 by LAN (Local Area Network, local area network), and two-way transmission is realized between the management server 20 and the managed server 10, and the management server 20 is used for UDP packet and TCP (TransmissionControl Protocol , transmission control protocol) data packets are mutu...

Abstract

The invention provides a system for redirecting serial data and a method thereof; wherein, the redirection system includes a client; the client is provided with a browser and is connected with a management server through HTTP; the management server is connected with a plurality of managed servers through LAN; the redirection method is achieved by the redirection system and comprises the following steps: the browser judges whether input information is acquired or not; when the browser acquires the input information, the browser can judge whether the input information is disconnection; if when the browser determines the input information is not disconnection, the input information is sent to the managed server through the management server; when the managed server receives the input information, corresponding information is returned to the management server; then monochrome text and color text on the managed server are output and displayed by the browser on the client. Therefore, a vacant serial port and serial cable used for connecting the serial port are not needed, and the invention can be applied conveniently.

Description

【Technical field】 [0001] The invention provides a serial port data redirection system and a serial port data redirection method, in particular a serial port data redirection system and a serial port data redirection method with convenient application. 【Background technique】 [0002] The console redirection feature allows maintaining remote servers by redirecting keyboard input and text output. The console redirection function can be used for BIOS setting, RAID setting, displaying POST process and executing programs under MS-DOS system. In order to use the redirection function, the user can usually use a serial cable to directly connect the serial ports of the server and the client, but the condition of this solution is that there are free serial ports on the client and the server and a serial cable for connection; A terminal emulator like HyperTerminal is required, and such software needs a higher version to support arrow keys and function keys. Existing solutions are limi...
