Yes. In documents labeled "Secret" and "Proprietary" and unavailable
without happening to know that for example the Transcend chipset is the
same as the Sure, and that the commands there also work on the Sure (
well almost all of them). That would be a pretty poor excuse if it were
given by the manufacturer.

Except for timing purposes the user might not want the 8 lines of output
that the sure delivers by default. They might only want one of them. If
the device is run at 4800 bd instead of the default 9600 those lines
might be too many for example. 

While it is true that the device does work out of the box, one might
want to change things, and for that a manual is crucial.
