Problems solved by technology

However, the biggest problem with this kind of Telnet program is the data security problem during the transmission process, because basically it is transmitted with a kind of source code similar to ASCII code, and the data will not be encrypted in any way during the transmission process. Therefore, when the host system 2 requires a remote user to enter an account number or password for online confirmation, the transmitted data, including the aforementioned input data, is likely to be stolen by hackers during the transmission process through the Telnet protocol.
Moreover, both the host system 2 and the computer system 8 of the above-mentioned known technology need to install the above-mentioned program conforming to the terminal emulation protocol respectively, and it is necessary to consider whether different operating systems can support the aforementioned terminal emulation protocol during installation. program, resulting in less convenient use

Abstract

The present invention discloses a remote terminal machine simulation system and its method. Said method includes the following steps: converting the data which is outputted by main machine system compatible with UNIX system and has serial signal format into packet format by means of an information conversion device; utilizing a network system to transfer the above-mentioned data into a remote computer system compatible with WINDOWS operation system, then utilizing a terminal machine simulation unit in said remote computer system to output a picture undergone the process of terminal machine simulation treatment on a terminal machine according to said outputted data, so that the remote user can make real-time monitoring or operation for said main machine system.

Description

technical field [0001] The invention relates to a remote terminal simulation system and method, in particular to a system and method capable of performing real-time remote terminal simulation on a host system via a network. Background technique [0002] At present, the terminal operation of some large host systems such as workstations or work servers, such as figure 1 As shown, the existing RS-232 interface (or port) of a PC-level computer 5 is directly used to connect to the host through a connection cable (cable) 3 with a 25-pin or 9-pin (pins) connector (connector) The RS-232 interface of the system 1, so that the user can monitor or operate the host system, that is, the host computer, by using a terminal such as a screen and an input device such as a mouse or a keyboard in the PC-class computer 5 The display information returned by the system or the control data input by the user from the input device will be converted into a RS-232 serial signal (SerialSignals) by the ...
