Default [Q] How to read CAVE settings in DFS?


I am attempting to read the CAVE settings in DFS but all I get is an error, "CPS_ERROR BAD_PARAM". I have entered my spc and I can read almost everything else in DFS (except ha and aaa which give me the same error). What am I doing wrong? How can I read CAVE, HA, and AAA from my phone?

p.s. I have done the open sesame door trick but could not find any valuable information in the 466 or 1192 files.
