devices. To minimize electromagnetic interference (EMI), use braid-shielded cables with metal ends when connecting a device to this port. The parallel port can operate in several different modes. The default mode for your computer is SPP (standard parallel port). However, your computer also supports the ECP/EPP (extended capabilities port/enhanced parallel port) mode. ECP/EPP has two advantages over SPP. When your computer is in ECP/EPP mode, you can print documents faster than when the computer is in SPP mode, and you can attach devices other than printers, such as communication and storage devices, to the parallel port. You can set modes of operation for the parallel port using the Configuration/Setup Utility Program. Serial Ports Your computer has two standard 9-pin, 16550-UART serial ports that can be used to communicate with devices such as modems, plotters, and printers. To minimize electromagnetic interference (EMI), use braid-shielded cables with metal ends when connecting devices to these ports. Universal Serial Bus Ports The universal serial bus (USB) interface is a new, emerging technology being developed to add more diversity and capabilities to personal computers. IBM has provided two, 4-pin USB connectors in your computer as a standard feature so you can be ready to take advantage of new USB devices as they become available. Using this new technology, you will be able to plug many different types of optional, USB-compatible devices into the USB ports on your computer. Because USB incorporates Plug and Play technology, you can install and remove devices easily without turning off your computer or opening the cover. Once installed, the devices configure automatically. In addition, an option called a hub can be connected to a USB port on your computer, which enables you to plug in more than one device at a time. A hub converts a single USB connector into multiple ports where USB devices can be attached. For more information, see the USB Web site (http://www.usb.org). For USB drivers, see the Microsoft Web site (http://www.microsoft.com/support). 6 Using Your Personal Computer

The parallel port can operate in several different modes.
