Hi Frank,
I suppose, Shell.ReadAll() doesn't assume an encoding: It should
just read bytes.
But, according to a recent discussion and my own experience,
Shell.RealAll()
isn't transparant. Certain characters get converted. Since this
conversion
behaviour isn't documented, I won't like to guess, which chars get read
transparently.
CU,

Hi Stefan,
thanks for the tip. Apparently it really uses Backspaces (0x08),
but the characters between them are all non-ASCII. I tried
diffferent encodings (UTF8, WinLatin1, MacRoman), none of them
produced a meaningful output.
Here's a hex dump:

Any ideas what encoding this could be? What encoding is the data
received by Shell.ReadAll() supoosed to be, anyway?
Cheers,

Save all characters to a text file and open it using a hex/text

I suppose, your data - the asterisks - is inside but you won't see
it on
screen, since the control chars do 'fun stuff'.
A shell process might switch to terminal mode, if it identifies
the caller
of an app as an interactive shell process connected to a capable
terminal.
In your case, the process should NOT switch to terminal mode.
Don't know, are actually generated, but I'd google for VT-52 or
something like that.
Here is what shows up, when I do an erase of an empty DVD-RW -
output of
drutil redirected to file and opened using vi:

Thus, drutil is oddly written :-(
