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.
Wake On Demand in Snow Leopard
Putting your Mac to sleep saves power, but it also disrupts using your Mac as a file server, among other purposes. Wake on Demand in Snow Leopard works in conjunction with an Apple base station to continue announcing Bonjour services that the sleeping computer offers.
While the requirements for this feature are complex, eligible users can toggle this feature in the Energy Saver preference pane. It's labeled Wake on Network Access for computers that can be roused either via Wi-Fi or Ethernet; Wake on Ethernet Network Access or Wake on AirPort Network Access for wired- or wireless-only machines, respectively. Uncheck the box to disable this feature.
