gammu

Gammu -the GNU All Mobile Management Utilities formerly known as MyGnokki2- is a full-featured cellphone manager for *nix and Win32. Its makefile knows about .debs and .rpms, it is incredibly easy to configure and -unlike Gnokii- it supports the Nokia 3200 (RH-31) right out of the box through an inexpensive DKU-5 cable.
Right now I’m using this simple /etc/gammurc under Debian GNU/Linux with kernel 2.6.12:

[gammu]
port = /dev/ttyUSB0
model = 3200a
connection = dku5fbus
synchronizetime = yes
#logfile = gammulog
#logformat = textall
use_locking = yes
gammuloc = locfile
startinfo = yes
gammucoding = utf8
rsslevel = teststable
usephonedb = yes

# gammu --identify duly reports
