cinterion radio bands

[Giacinto Cifelli]

Dear Aleksander, all,

I am starting a new thread because I think the previous one was
filtered as spam, maybe when I added the log?

I collected some more modems and did more tests, and with an ALS3
(supported maybe as PLS8), which uses the single AT^SCFG: "Radio/Band"
value for all technologies, the crash of the demon does not occur.
And this with the patch I am developing, not only with the legacy one.

Therefore I thing there must be something wrong with my memory
management in the new code, but I don't see where, nor Aleksander's
review highlighted some problems in that sense.

Regards,
Giacinto
