This is the best clue I have found so far:-
Long Form: G997_DeltHLOGGet
Short Form: g997dhlogg
Input Parameter
- DSL_uint16_t nLine
- DSL_AccessDir_t nDirection
accessdir na = -1
upstream = 0
downstream = 1
Output Parameter
- DSL_int_t nReturn
- DSL_uint16_t nLine
- DSL_AccessDir_t nDirection
accessdir na = -1
upstream = 0
downstream = 1
- DSL_uint16_t nMeasureTime
- DSL_uint8_t nGroupSize
- DSL_uint16_t nNumData
- DSL_uint16_t nNSCData
Now, when you did get a response, it seems to have followed the output as above.
However, you were attempting to use line 0, direction 0 & also line 0, direction 1.
It may just be worth giving it a shot at line 1?
i.e. echo "g997dhlogg 1 1" > /tmp/pipe/dsl_cpe0_cmd
& echo "g997dhlogg 1 0" > /tmp/pipe/dsl_cpe0_cmd
