simple answer: you can’t
workaround/solution: you write a boxeater that watches for the known dialog (you know the text + you know the button ~= you know the dialog) and send the known response to the dialog.
drawbacks: it’s lame. (but it does work…)
slightly more complex answer that looks better in the beginning but proves to be useless across more vendors: there is a capability in the twain spec to see if the device is online ( search the forum and/or the spec for ‘online’) but with 99.72% of the devices I’ve tested it with it doesn’t do any good.
write a boxeater.
