That was exactly my intention.   The 5000 milliseconds timeout was sugg-
ested by Louis because the scanner is connected via WiFi.  But even with
these specifications  former versions of "scanimage" stubbornly produced
six timeouts of 1000 milliseconds each,  so I suspect  even former vers-
ions misinterpreted the default value  as a minimum as you point out be-
low.

So the code clearly contradicts the documentation.  I would vote in fav-
our of the documentation  and would prefer  the default value to be only
assigned, if the configuration files don't provide any timeout values.

Thanks, Olaf, for pointing this out.

Sincerely,
