Wireshark · Ethereal-users: Re: [Ethereal-users] Need to display color for "no standard" modbusfunction code

["Olivier Biot" <ethereal@xxxxxxxxxx>]

Regarding your 1st question, try the "bitwise_and" operator in the display 
filter. Remember that any display filter expression (including the ones you 
enter as a color filter) always evaluates as either true or false.

Best regards,

Olivier

Hello,

First of all I d like to thank you for this amazing analyser which is 
ethereal

I have loaded the latest version of ethereal (0.10.6) but I use it for a 
while
Windows XP OS

In fact I would like to (display at least) some modbus function code which 
are not in the standar library

My question is :
Is there a way to display into a modbus datagram specific color depending 
(unknown) function code ?
I thought the or_mask function could do it but I can't make it running :(

The other thing is :
Is there a way to add specific function code into etheral in order to 
increase modbus known request without going into source code ?

Last thing
If there is no other way to go into the C where shall I find modbus 
"description" in order to add my own request list

Thanks by advance for your feedback and your help
Best regards
Jerome
