For example, you may not see a printer listed, although you know one is attached to your computer. Instead, the printer is listed as a parallel port. The computer recognizes the parallel port as LPT1, which is an address that tells the computer where to send outgoing information and where to look for incoming information. Because your printer is a parallel communications device, the computer recognizes the printer by its LPT1 address and identifies it as a parallel port. You can test your printer connection in the Parallel Ports tests. Back to Contents Page to use them. Keys Explains the functions of the all of the keystrokes that can be used in the Dell Diagnostics. Device Group Describes the test group that is presently highlighted in the Device Groups area on the main menu screen. It also provides reasoning for using some tests. Device Describes the function and purpose of the highlighted device in the Device Groups area. For example, the following information appears when you select the Device Help category for Diskette in the Device Groups list: Diskette Drive A The diskette disk drive device reads and writes data to and from diskettes. Diskettes are flexible recording media, sometimes contained in hard shells. Diskette recording capacities are small and access times are slow relative to hard disk drives, but they provide a convenient means of storing and transferring data. Test Provides a thorough explanation of the test procedure of each highlighted test group subtest. An example of the Diskette subtest floppy drive Seek Test is as follows: Diskette Drive A - floppy drive Seek Test This test verifies the drive's ability to position its read/write heads. The test operates in two passes: first, seeking from the beginning to ending cylinders inclusively, and second, seeking alternately from the beginning to ending cylinders with convergence towards the middle. Versions Lists the version numbers of the subtests that are used by the Dell Diagnostics.
