v.what? -- A typo bit us in last week's issue. The article on the PSI PowerModem incorrectly said that the modem uses v.32 error correction and v.32bis compression - those numbers should be v.42 error correction and v.42bis compression. Sorry for the confusion - the modem supports the v.32 and v.32bis communication protocols, which define the connection speed (9,600 bps or 14,400 bps), but are different from the error correction and compression protocols.
Sleep (and Lock) Your Screen
When you are walking away from your computer, it's fairly common practice to start your screen saver and lock your screen. But did you know that there is a built-in keyboard shortcut in Mac OS X to sleep the screen?
Press Control-Shift-Eject and your monitor sleeps without engaging the screen saver.
