Peripherals Test

When you choose the Peripherals Test, selection 8 on the Main Menu
screen, the program tests each of the ports. (The printer test will be
executed only if a printer is connected to the computer.) The test
screen is displayed as each peripheral is passed (see Figure 4-29). If
any of the peripheral devices fail the test, one or more of the messages
shown in Figure 4-30 will be displayed.
