SIGSTOP is generally reserved for "suspend this program", not "kill 
this program".  Furthermore, according to the POSIX spec (and the BSD 
and Linux man pages, at least), you can't catch or ignore it.

If by "from the command line" you mean "with a 'kill' command", you can 
send SIGINT with a "kill" command - "kill -INT" or, on older systems, 
"kill -2".  You can also send it with your interrupt character if 
you've run Ethereal from a terminal window.
