Actually there's a better way (sorry, I was a bit jet-lagged yesterday).
You can use the '-z' debugging command line option to turn off certain
network optimisations.

The one you probably want it 'cavern -zd mysurvey.svx', but you can use any
combinations of the letters 'l', 'p', and 'd' after the '-z'.  Repeating
letters has no effect.  Order is unimportant.

Cheers,
