Diskette Change Line
The Diskette Change Line selection verifies that the diskette drive
Format a Diskette (for diagnostic use only)
The ADVANCED DIAGNOSTICS program requires that a diskette be formatted for each diskette drive being tested. This utility is not the same as the operating system FORMAT command. A diskette formatted for diagnostics can be used for diagnostics only, unless it is reformatted using the operating system.
NOTE: To fully test a diskette drive, use the highest capacity media intended for the drive.
Monochrome Video Board
For a description of this test, see “Video Tests” described previously.
Asynchronous Communications Interface
The Asynchronous Communications Interface test verifies interface data and control lines, baud rate, internal loopback control circuitry, external loopback circuitry (if a loopback plug is attached), as well as clock and calendar functions (if applicable).
NOTE: This selection tests all asynchronous communications interfaces. Before selecting this test, be sure you know which device is set to COM1 and which is set to COM2. This is necessary to deter- mine the applicability of any messages or error codes that may appear. For more complete testing of an asynchronous communications interface, attach a loopback plug.
