From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Yes, and encryption had nothing to do with it (though I suppose it would have prevented it in this case).
A properly configured modem would ignore this coming from the Internet side, or escape the characters so that they didn't form that string.
Encryption would prevent it - that's what I meant :)
I think the trick is to convince someone to send that string, so the modem sees it coming from the computer. Similar to tricking someone into pressing Alt+F4, or Ctrl+Alt+Del twice on Windows 9x (instantly reboots without prompting).
encryption would prevent the modem from seeing it when someone sends it, but such a short string will inevitably appear once in a while in ciphertext too. so, it would actually make it disconnect at random times instead :)
(edit: actually at seven bytes i guess it would only occur once in every 72PB on average...)
