Thank you very much for your quick reply.

This was caused by an old version of tshark as you suspected.

Thanks again all!

Hi All,

I am currently making some changes to some automation software that uses 
tshark's output. My development has been primarily in a linux 
environment and is tied to wireless lans. I have noticed that tsharks 
default output is different between a windows & linux machine, and 
essentially I am hoping to get the nice "Flags" bitmap that appears in 
linux, to appear in windows.

For example, currently I am using

tshark -r (filename) -z proto,colinfo,frame.len,frame.len -z 

here is the corresponding tshark output:

34659 372.477882 OUI_05:02:a9 -> OUI_34:cb:0e IEEE 802.11 Data, SN=285, 
FN=0, *Flags=.p.....TC*  wlan.bssid == 00:00:00:79:37:70  frame.len == 408

34659 372.477882 OUI_05:02:a9 -> OUI_34:cb:0e IEEE 802.11 
Data,SN=285,FN=0  wlan.bssid == 00:15:70:79:37:70  frame.len == 408
What versions of Wireshark are you running? The "Flags" string was added 
to the Info column in 2007, about 6 months before the 1.0 release.
