This line of text is terminated by a "line feed."
Or maybe by a "carriage return" followed by a "line feed." You see, the text I am writing, and that you are reading, is written in ASCII which is based on the Model 33 Teletype. On a Teletype, a carriage return character (0x0D) would cause the print head to travel all the way to the left; a line feed (0x0A) would cause a roll of paper to move vertically upward by one line.
The modern experience of "going online" is derived from the fact that the Model 33 Teletype had a rotary switch that controlled an electric motor. This switch had three positions, "Line," "Off, and "Local." At my high school, one prepared computer programs in BASIC using "Local" mode so that the program could be punched onto paper tape, one character at a time, while the Teletype was disconnected from the computer system.
Use of computer systems had to be paid for according to the amount of time used, measured in seconds or even milliseconds. Computer time was then too expensive for a user to be allowed to sit at the Teletype keyboard and manually enter keystrokes; instead, after the entire program was punched onto paper tape, the switch would be turned to the "Line" position and the paper tape reader would cause the program to be transmitted to the computer at the Teletype's maximum speed of 110 baud. This was known as "going on Line."
Early microcomputer systems, like larger computers, used Teletypes as I/O devices and ASCII was used internally to store and interpret alphanumeric data. This continued long after users migrated from Teletypes to video display terminals, e.g. DEC VT-100, and then to the IBM PC as the I/O device of choice. Many special function keys from the Model 33 remain in use to this day, for example the Esc (0x1B), Ctrl, Backspace (0x08), Tab (0x09) and DEL (0x7F) keys. The DEL (Delete) code is 0x7F because hitting DEL would cause all the holes in that row of paper tape to be punched (get it, 0x7F). So if you made a typing mistake you could back up the paper tape by one character and type DEL, this would punch through your errant character and the computer would ignore the DEL character.

c# what a lousy name
with all the letters in the ascii table why can't you get past C http://www.asciitable.com/

Re:BUT THEY ALWAYS SAY THAT!
Remember how in the past, each and every time, all the innovative sounding promised new features weren't in the actual shipped product, except for maybe an evil or annoying one?
Sorry, but when reading MS press releases, I switch to politician mode.
Rule 7783: If it exists, it's a lie! ^^

Re:On units and their prefixes
> If the HTML ascii code (e.g. é=é) is greater than 255...
It should have been: "If the HTML code (e.g. é=é) is greater than 255"...
ASCII codes can't be greater than 255 and this is extended ASCII
;-))I realize that you already seem to understand this, you probably just made a mistake typing...

Light pollution
Since we still pump large amounts of light into space from street-lighting around the world would that not be easier to detect than a few encoded radio signals?
Even if they detect a digital signal they still have to demodulate it to this obscure 'base-2' encoding we use over here because it works well with our equipment they have either grown out of or never discovered, after that they might decide to visit asciitable dot com to find out what it actually means.
Maybe we can buy out Arecibo and continuously waste a few megawatts at broadcasting a "Hello?! Can you hear me now?" analogue recording -

Decimal 70: 'F'
Decimal 85: 'U'
Decimal 67: 'C'
Decimal 75: 'K'That's it. Maybe I wasn't clear. Sorry.

Re:solved within 7hrs...
Further to my previous post, E3 is the hex representation of the ASCII code for pi:
ASCII Table
It's 227 in decimal. -
Re:Cut & PasteIt's slow, but you could look for the letters/numbers/symbols you need on the web. ASCII tables could be a good place. Many software key loggers also keep track of clipboard history.

Re:1999 UK all over again?
Hold the right alt key and type 156 using the number pad. If you use a laptop, press alt, then the function button, then 156. Do not use the number keys above the alphabets. See http://www.asciitable.com/ for more characters.

Re:Shome mishtake shurely?
FYI - you can fairly easily represent extended ASCII characters in HTML.
Format: & # 123 ; (without spaces: ampersand, hash, numeral, numeral, numeral, semicolon)
A quick lookup of an ASCII Table shows that _ _ ('e' with a circumflex) is ASCII 136.
EDIT: Looks like
/. does not allow use of the the extended character syntax in the "HTML Formatted" template. Between the two underscores above I put in the necessary char code, but I'm not seeing the character in the post preview. Oh well. Nevermind. -
This one's fun to debug - perl via urlI got this on a few servers yesterday- first thought it was related to the < PHP 4.3.10 bugs- it's not.
This exploit is actually quite clever. It inputs values into the URL field that use the chr() function in PHP to pass text. It then writes its own perl script and executes it on the server.
Here's the first line from the logfile:

If you decode the ascii characters, you get:
perl -e "open OUT,q(>m1ho2of) and print q(HYv9po4z3jjHWanN)"
I didn't have enough freetime to decode the whole thing due to.. actual work having to be done, but it's quite clever.

Re:Out of letters.
I mean, what can come after zed?
Well, according to the ASCII table, it is the "[" character.
