|Or, you could actually use something designed to do this job, and it wouldn't really cost you much more: BayTech makes some pretty good stuff for both remote access and remote power control. You can reach them at http://www.baytech.NET (Note that baytech.COM is wrong.)|
A box to do just remote access will set you back about $250, or a somewhat more if you want some more ports or advanced features (modem cards, PPP, add'l interface cards, etc.) The DS series does the terminal server console access only, the RPC series are remote power controllers, and the DS-RPC series put both functions in one box. If you need more than a couple of ports, it's hard to beat their prices even by rolling your own, so check them out.
