Hello Pascal,

Yes, I do, but I really expected that to be (similar to) expert items, not
some "spam" taht (optically) interfers with the normal output of tshark.

Sigh. Is _ws.* documented in one of the manpages? I couldn't find it. And the
only mention I could find (the tshark manpage) used a small 'i'.
Could we plese agree to either *always* use small letters or to make the
filter names case insensitive? Also:
=========
$ tshark -T fields -e asdf
** (process:13516): WARNING **: 'asdf' isn't a valid field!
tshark: Some fields aren't valid
$ tshark -T fields -e _ws.col.info
Capturing on 'Wi-Fi'
^C
21 packets captured
[email protected]:~/firmatmp/salalah/WIP/tests/radius$ tshark -T fields -e _ws.col.asdf
Capturing on 'Wi-Fi'
=========
Should we try for a bit more consistency here?

Thanks again
   Jörg

We are stuck with technology when what we really want is just stuff that
works. Some say that should read Microsoft instead of technology.
