Please consult the Handbook and google, I'm sure there's nothing difficult to it. I would not support your chaining idea, though. It's the only one that requires $0.00 budget, but COM hubs are cheap today. If you rent rackspace, I'm sure your colocation provider can offer you some kind of non-expensive remote management. If rackspace is free, consider buying some hardware (like a COM hub). The matter is, that you'll want 9600 bps speeds for max compatibility. While it is usable for occasional failure recovery, chaining it would make it lag too much.
