Thanks to Casper Dik, Darren Dunham and Luc Suryo for their 
responses....I should've thought to look at the tunable parameters 
manual and I would've seen what I needed. (sudo wasn't an option for 
this case for other reasons).  The 'mdb'/'adb' command looks to be what 
I need.

software...oh wait, you may never see this since I'll never click to 

Darren's response was the most feature rich so I'm quoting it...
