CHAPTER 5: Utility Software

“1” will result in the diagnostics being run once.

“2” will result in the tests being run a user-specified number of times. (This mode is useful when searching for an intermittent problem.)

“3” exits the diagnostic program and returns control to MS-DOS®.

If option “1” on the main menu is selected, the diagnostic tests are run once. If any test fails, an error code and error message are displayed. Otherwise, if the main tests run successfully, the user is asked whether the online tests should be run.

If you enter “NO,” several tests run which check the Adapter in an offline mode.

If you enter “YES,” the Adapter must be connected to the host. A list of active addresses is then displayed, and you are prompted for the station addresses to use. Either one primary address or a primary and a secondary address may be entered.

NOTE

Enter an “N” for the secondary address if only one address is to be used. If only one address is entered, this address is used twice during the tests.

If all tests run with no errors, the message

Test Complete

is displayed, and you are prompted to hit any key, which causes the main menu to be redisplayed.

If option “2” on the main menu is selected, the diagnostic tests are set to loop. You are then asked how many times to loop. This loop count may be set from 1 to 999 times, with an entry of 0 indicating loop infinitely.

NOTE

The PC must be rebooted to cancel the infinite loop.

You are next asked whether the diagnostics should pause when an error is detected.

If the response is “NO,” any errors detected by the diagnostics are displayed; however, the diagnostics will immediately clear the screen and restart on the next pass of the tests.

If you respond “YES,” any error detected is displayed and you must hit the <ENTER> key to continue.
