I searched with fgrep(1) in the installed binaries where this "%CPRI=0"
is located; it is in /usr/lib/cornucopia/modules/fsogsm/modem_ti_calypso.so:
root@om-gta02 /usr/lib/cornucopia/modules/fsogsm # fgrep '%CPRI=' *
modem_ti_calypso.so:%CPRI=1
modem_ti_calypso.so:%CPRI=0
I changed this with a hex editor and now also after suspend/wakeup the
modem is initialized correctly to show the encryption state during
calls;
This should be fixed in the sources; and I will file a bug report in
Trac;
as a change request remains that the encryption state should be visible
in the desktop while making a call, maybe even as a pop-up message when
the call is not done encrypted, like:
Call is NOT encrypted!
Perhaps man-in-the-middle-attack,
do you really want to continue the call?
Thanks
