The original ASCII used 7 binary bits. The encoding has a total of 128 code points 0 127. This encoding soon became a worldwide standard. Among the 128 code points, the 0 No. 32 and No. 127, a total of 34 characters, are control characters or communication-specific characters. Among them, No. 32 is a space. Space No. 33 No. 126, a total of 94 visible characters, including Arabic numerals, English letters, English punctuation, etc. All these 94 characters can be entered directly through the standard keyboard 3.What is ASCIIArt ASCIIART uses the combination of these characters defined by ASCII encoding to reflect things in real life or the art of expressing one's thoughts Now we don't have to be limited to using only ASCII-encoded characters. For example, we can use GB code or even GBK code. Create with all characters in Taiwan uses BIG5 code. With more characters, more things and artistic conception can be passed through. Character drawing is used to represent it. Of course, its versatility is worse than standard ASCII. Although the character set has been expanded, it is still called ASCI. IART 3.What are ANSI escape sequences? ANSI is the abbreviation of American National Standards Institute, which is the American National Standards Institute. . ANSI escape sequences can be regarded as a series of functions used to change the display mode, control the movement of the cursor and even You can redefine keys, etc. On BBS, you only need to get part of it. The most commonly used one is the setting of background and background colors. If set, other control codes such as cursor control, screen clearing, etc. can be used to create special effects in some specific situations. In addition, some terminal software such as cterm also define some non-standard control codes. 4. Etiquette The production of AsciiArt is a very time-consuming job, so each work contains the author's sweat and effort. It is difficult. Therefore, when using other people’s works, it is best to obtain the consent of the original author before using the work when reprinting or communicating. Please indicate the original author and explain that the work is a reprinted work and try not to change it. Respect the work and respect the author. Is a basic requirement for every AsciiArt maker and enthusiast 5. Learn to use *Term As we all know, there are two ways to log in to bbs: web and telnet, while ASCIIArt art is only available under telnet. Only then can you appreciate its perfect effect. Therefore, when learning ASCIIArt, you must first learn to use telnet to log in to the workstation. Various term software can be used It is hoped that during the training process, all students will be able to use telnet mode to access the forum and complete their studies. resource Various terms and tools for making ANSI can be found on Guanghua’s homepage. Please download them yourself. Reading material Familiar with the use of *Term ANSI version x 8 3 3 x refers to the essence area, 8 is the 8th directory, and so on.
