9-3-2 Checking Results
The results of the internode test are stored in the fourth through ninth words of
the portion of the CPU Bus Unit Area allocated to the Ethernet Unit. The status
information area stores the test status and numbers of test runs and errors.
Test Status
The result of the test run and descriptions of errors are stored as the test status.
The test status is stored at the word whose address is calculated by the following
formula:
Word = (100 x unit number) + 3

Note The internode test does not count errors when a routing table error or send pa-
rameter error has occurred.
Error Flags
The bits corresponding to errors are turned ON if errors occur. The flag status is
maintained until the internode test is run again.
Number of Test Runs and Errors
The number of test runs and total errors from the time the test is started until it is
stopped is stored. The configuration of this area is shown in the following table.
Each result is stored at a word relative to the first word the address of which can
be calculated using the following formula:
Word = (100 x unit number) + 4 to +8
