HELP
-
This option causes a list
of
the TEST options to be output.
TEST
LOGICAL
-
This test
is
intended to detect
RAM
errors that are more difficult to detect.
It
is a more exhaustive
RAM
test on the MDR-2000. The records stored in the buffer
RAM
have
their checksums recalculated and compared with those calculated when the record was stored. This
is
a more exhaustive test but since it is a logical test it will only examine those memory locations
that have stored, but as
of
yet uncollected, data.
If
the MDR-2000 buffer is empty then this test will alwa
ys
complete successfully,
if
the buffer
is
full then this test is most effective.
For convenience the LEDs will display the progress
of
the test. The display corresponds to the ones
complement
of
the record count remaining to be checked, divided by 256.
It
is provided as an
indicator that the test
is
progressing since with large buffers filled to near capacity the test will take
a several minutes to complete.
TEST NVR -
This test performs a checksum test on the non-volatile
RAM
.
TEST
PORT
-
This test dumps a continuous test pattern over the modem port.
It
is used to test the
port or host interface. The test is terminated by entering <Control-C>.
TEST RAM -
This test performs a simple read and write test on the processor memory. This is a
non-destructive memory test and as such
is
not exhaustive. Therefore it is only conclusive when
hard memory errors occur. This test can be interrupted by pressing <Control-C
>.
