self-test
When the modem is turned on, an automatic self-test is performed, which tests:
•
Its program memory
•
Its data memory
•
Its stored memory
•
Its data processing unit
The test lasts a few seconds and ends with a series of:
•
Different tones if the test is ok,
•
The same tone if a failure is detected. This failure is stored in the S19 register or detailed by
the ATi7 command. See chapter 6 "Troubleshooting".
The self test result is displayed on the front panel LCD of the 2885 SDV version.
