OK. At least the version of TimeLab that I had on the first laptop I
grabbed where unable to get useful data from the CNT-90.
When running in "Native" mode, all I get out of it is the identity
string. Measurement chokes on the identity string.
When running in "Compatible" mode, I did get the HP53131A driver get the
identity string and then bogus values, but getting measurement chokes on
the identity string and then dieas.
If someone could put a CNT-90 in John hands, I'm sure that he can make
it talk sense based on the CNT-80 driver. The manuals (including
Programmers manual) is available from Flukes online.
CNT-90 does not have talk-only mode. It's a design choice I know they made.
