Hi Richard,

I was just going over your patch for uisp and saw this hunk from DAPA.C:

I think originally the DT006 case was falling through to the MAXI case. With 
you patch it now falls into the ETT case.

It seems to me that hunk should look like this:

Was there any specific reason you decided to put the PAT_ETT between DT006 
and MAXI?

If not, I'll go ahead and commit your patch with my version of that hunk.
