Пакет scmxx: Информация

SCMxx is a console program that allows you to exchange certain types of
data with mobile phones made by Siemens. Some of the data types that can
be exchanged are logos, ring tones, vCalendars, phonebook entries, and
SMS messages.

It works with the following models:
 S25,
 S35i, M35i and C35i,
 SL4x, S45, ME45 and C45
and probably others.

It basically uses the AT command set published by Siemens
(with some other, additional resources).
