Sounds reasonable for me. I'm now waiting for a description of that option to add to the SANE2 standard :-) Any volunteers? Bye, Henning

is there a function in sane to ask if the document feeder is loaded (like the 'has feeder loaded' option in TWAIN)? Thanks Oliver

Here's two typical TWAIN conversations (with an HP): Do you have a feeder? -Yes Can you tell me if the feeder is loaded? -Yes Is the feeder loaded? -I don't know Is the feeder enabled? -No Please enable the feeder. -OK Is the feeder enabled? -Yes Please disable the feeder. -OK Is the feeder enabled? -Yes Phil

there was some discussion about having one or more sane options that could provide scanner status. they would have to be in a specific group, or have specific indexes into the options array, or have specific names, so finding them could be sort of ugly. i can think of a few things that the fujitsu scanners tell us: button1 pressed button2 pressed character on 'function' readout number on 'copy' wheel paper in hopper cover open lamp warm is there a general purpose way to expose this? allan On Tue, 16 Dec 2003, Oliver Schirrmeister wrote: is there a function in sane to ask if the document feeder is loaded (like the 'has feeder loaded' option in TWAIN)?
