Introduction: Hacks #75-84

As you travel through a PC system from the inside to the outside, you end up at the I/O, or Input and Output systems: serial, parallel, game, USB, and IEEE-1394 ports. There isn’t a great deal here—just a couple of ports that slog along at what seems like a snail’s pace compared to blazing CPU speeds and outrageous disk drive transfer rates—but what you do have can use some understanding and hacking to get them shipshape. By shipshape I mean working at the speeds they are supposed to, not conflicting with other devices or themselves, and operating in the correct mode for the peripherals connected to them.

While you shouldn’t look for any spectacular performance boost in your I/O ports, they can be one of the most frustrating parts of a PC to deal with if things do not work right.
