wvdial does not disconnect after ctrl-c

[Ranjan Maitra]

Hi,

I have been using wvdial (briefly) and I have a strange outcome when I
disconnect. This happens about 90% of the time. About 10% of the time,
it exits cleanly and everything is fine, but my question pertains to
the other 90%.

So, I hit ctrl-c and get the following

^CCaught signal 2:  Attempting to exit gracefully...
%

There is no wvdial process anymore.

$ killall wvdial
wvdial: no process found


However, the connection is not terminated (the meter is running), and indeed, 

$ ps aux | grep wvdial

So, how should I really disconnect wvdial now? 

I am using a very up-to-date Fedora 14 on a (IBM) Lenovo Thinkpad T61
(on which sound has never worked after Fedora 13).

Many thanks and best wishes,
Ranjan
