Troubleshooting Terminal, Printer, and Serial Device Connections
Testing the DTC
If the DTC is suspected as the cause, TermDSM can be used to determine
the hardware or software component involved. It also provides DTC dump
and reset functions.
CAUTION TermDSM functions described in this section cause all sessions
on the DTC to abort. Data for each session can be lost. Verify
that users are logged off before attempting these tests.
Security level 1 (SM or DI capability) is required for the following
functions. For details on using TermDSM, refer to chapters 3,
"Introduction to TermDSM" and chapter 4, "TermDSM Commands."
The DUMP DTC command writes data to a disc file from the software
managers serving all the ports on the DTC. The dump file can be read by
an HP support representative for detailed diagnosis of software faults.
After the dump, the DTC selftest is run automatically.
The DTC selftest exercises the following: the DTC processor card; the
serial interface cards; and the connector cards. The selftest runs for
about 2 minutes. After the selftest, the DTC is downloaded and reset
automatically. If you are running TermDSM at the console, messages will
be displayed informing you of the download.
The selftest isolates faults within Field Replaceable Units (FRU) in the
DTC. The faults are indicated by TermDSM messages and by error codes
shown on the DTC's LED display. For information on servicing FRUs and
reading DTC error codes, refer to the:
