This jack lets you connect to a LAN. The adaptor has
built-in support for Ethernet LAN (10 megabits per
second, 10BASE-T) and Fast Ethernet LAN (100 megabits
per second, 100BASE-Tx).
This indicator glows green when the computer is
accessing the LAN.
Use this 9-pin port to connect external serial devices such
as an external modem, a serial mouse or printer.
The Universal Serial Bus (USB) port enables chain
connection of a number of USB-equipped devices to one
port on your computer. For example, you might connect a
USB-HUB to the computer, then connect a keyboard to the
USB-HUB and a mouse to the keyboard.
Use this port to connect an external PS/2 compatible
keyboard or mouse. The computer automatically recog-
nizes which device you have connected when you turn on
the power.
