![]() and so I decide to make a new /etc/issue for myself.įirst I worked on the logo, which after a few attempts I decided to just accept how slashes "fall" because trying anything else just turns out like a Christmas tree, then with the inside of the logo done using full stops I had a crack at the font. ![]() Fast forward to now, when X has completely died (majorly buggy graphics configuration), I'm entirely in textmode (framebuffer - I just won't go there, too much work). Some time ago, I learned how agetty (the program that displays /etc/issue and manages login) is able to display certain types of "non-static" information by way of specific "escape sequences" that were agetty's own. NOTE 2: This has a known bug - if your screen is 80 columns wide and your hostname is over 11 chars long, due to the layout of this file it will wrap to the 2nd line. NOTE: If you have no idea what "/dev/vc/1" or "text console" or "tty" means, know that these don't interest you and/or you don't find these interesting, or you boot to runlevel 5, this isn't for you. block ) ASCII code 24 = CAN ( Cancel ) ASCII code 25 = EM ( End of medium ) ASCII code 26 = SUB ( Substitute ) ASCII code 27 = ESC ( Escape ) ASCII code 28 = FS ( File separator ) ASCII code 29 = GS ( Group separator ) ASCII code 30 = RS ( Record separator ) ASCII code 31 = US ( Unit separator ) ASCII code 127 = DEL ( Delete ) Printable ASCII characters :ĪSCII code 32 = space ( Space ) ASCII code 33 = !

In this way was added the ASCII characters ranging from 128 to 255. Also 128 characters were added, with new symbols, signs, graphics and latin letters, all punctuation signs and characters needed to write texts in other languages, such as Spanish. In 1981, IBM developed an extension of 8-bit ASCII code, called "code page 437", in this version were replaced some obsolete control characters for graphic characters. So with this set of only 128 characters was published in 1967 as standard, containing all you need to write in English language. This code arises from reorder and expand the set of symbols and characters already used in telegraphy at that time by the Bell company.Īt first only included capital letters and numbers, but in 1967 was added the lowercase letters and some control characters, forming what is known as US-ASCII, ie the characters 0 through 127. The American Standard Code for Information Interchange, or ASCII code, was created in 1963 by the "American Standards Association" Committee or "ASA", the agency changed its name in 1969 by "American National Standards Institute" or "ANSI" as it is known since.
