Unless your device supports CAP_EXTENDEDCAPS seperate settings means seperate acquisition – you can’t renegotiate capabilities while an acquisition is underway without CAP_EXTENDEDCAPS.
The mirc string via twain is trickier. If you post the model you may be more help from someone with (more) mirc experience.
If I were trying to find it I would (start sweating, then) run a Msg_Get a few hundred past x8000 to see if there is a customCap out there waiting with string info I’d look thru all of the standard extednded imageinfo and another 2 or 300 hundered to see if the mirc string is there.
Otherwise you’re at the mercy of the vendor’s support staff and documentation for how to get the info out.
the part where you ask “A optimal time for do the images acquisition is also requested.” … you’ll have to try asking again with different word. I didn’t understand what you’re looking for there.
