Hehe.  It looks like my effective taking of the stewardship of this
modem firmware is not such a bad thing for the community after all. :)
Or at least for what's left of the FR user community...

I wonder though how Dieter acquired that knowhow back in the day - did
he previously work for some other modem or dumbphone manufacturer that
used TI chipsets?  Or maybe even for TI-Berlin (former Condat GmbH) or
somesuch?

Ouch!

Stories like this make me wonder how many other bugs of similar nature
might still be lurking in those closed binary libs.  That is one of
the reasons why I seek to produce a "hybrid" Calypso fw by combining
the RTOS environment / drivers / BSP pieces from the TCS211 source
(the one leo2moko was built from) with the GSM stack source from the
LoCosto find - it will give us a fully functional modem fw without any
binary blobs!

Whoever originally liberated the TCS3.2 (LoCosto) source which I found
at <http://scottn.us/downloads/peek/> in 2013-05 (through a Google
search!) is a real hero.  If it wasn't for this leak, the only C source
we would have had for the core GSM stack would have been the TSM30
version from 2003, i.e., a definite backward step from the TCS211
version given in binary form to FIC, Foxconn (Pirelli DP-L10) and a
bunch of others in the 2007 time frame.
