I've changed because as you can see in
http://www.kannel.3glab.org/cgi-bin/viewcvs.cgi/gateway/gw/smsc_at2.c.diff?r
1=1.24&r2=1.26

line 759+, it was returning -10 and everything worked because every other
line that called this
function were expecting a -1 as error and therefore we never got an error.

When I corrected the -10 to -1 at revision 1.25, every check started to work
but CPIN don't,
because some modems reply with the +CPIN and OK and other don't (or reply
the OK much
later).

I'm now doing some patches to at2 ;) and double-checking everything with my
ericsson and nokia.
