Hello everybody,
this is a scanimage output generated in a VIO window trying to scan
with an Epson GT-300 parallel scanner.

These are the messages on the start sequence:

scanimage printed a sequence of similar messages, then added things
like this:

[epson] receive buf, expected = 1, got = 1
[epson] code 02

...

and also this:

I tried to stop it with Ctrl-C, but then the entire window became locked
and it was impossible to kill the process (altough it was present in
the Window List).

I tried with another window without copying the reports from the window,
and when I tried to put a sheet in the feeder of my scanner, the scanner
itself didn't respond. After a shutdown of the scanner, I retried and
the sheet was correctly fed. So I retried to scan without doing other
copies from the VIO screen, and scanimage printed a series of strings
which I couldn't read, very different from the other I listed above.
Then it printed the same output I wrote above, and continued like this:
when I tapped Ctrl-C, it did the same thing (blocked making it impossible
to close window). After another shutdown of the scanner, I did a third
try, this time to try and capture that odd output I saw in the second
try. Here is some:

[sanei_pio] reset
[sanei_pio] ctrl on port 0x, though the sheet was brought out by the
scanner (This is probably scanner behaviour on a scanning error or the
like).
I used the command "scanimage -d epson" for all the three tries.

PN: scanimage is still printing messages, at least 5 minutes have
passed since I launched the third session.
