Hi!

Ok, here we go... a modified version of sanei_wire.c. Could please try
this one? with sane_debug_sanei_wire=4...

| Hi!
|
| The problem here is, my net backend just doesn't crash, no matter what i
| do :(
|
|
| I'd say this is the old "scan over localhost" problem. Anyway, I've

|
| Please try this backend with SANE_DEBUG_NET=128 and send me the output...

| | Any explanation for this ?
