Installation
Once you have plugged the USB Data cable and the T230 phone, you may have:

root@smsserver:~# lsusb
Bus 001 Device 002: ID 067b:2303 Prolific Technology, Inc. PL2303 Serial Port
Bus 001 Device 001: ID 0000:0000
root@fr-c400-0257-l:~# ls -la /dev/ttyUSB0
crw-rw---- 1 root dialout 188, 0 2007-03-22 10:17 /dev/ttyUSB0
root@smsserver:~#


You can test your configuration using minicom

root@smsserver:~# minicom -s


-s is for minicom setup on launch. You may configure the serial port to /dev/ttyUSB0 and the speed to 9600 8N1.

Welcome to minicom 2.2

gnokii settings
Edit the /etc/gnokiirc file:

port = /dev/ttyUSB0
[...]
model = AT
# model = 6510
[...]
use_locking = no
#use_locking = yes
[...]
serial_baudrate = 9600
# serial_baudrate = 19200

The use_locking setting has been modified as it may happen that I send SMS to more than one people at a time. The solution would be to use smsd…

From Mail to SMS

As we are using postfix and procmail, root user may not be used!
Let’s create a itroot user that will be the recipient of email notification to be turned into SMS.
Create a .procmailrc file for this user. A convention will be used for notification emails. The subject will contain [SMS] and only the subject of the email will be transfered as an SMS:

DEFAULT=/var/spool/mail/itroot
MAILDIR=$HOME/Mail

:0
* ^Subject:.*\[SMS\].*
| cat - | awk -F":” ‘$1 == “Subject” { for(i=2; i <=$NF; i++) $(i-1) = $i; print $0 }’ | sudo /usr/bin/gnokii –sendsms 06XXXXXXXX >> /var/log/SMS.log 2>&1


As you can see, due to permissions issue, itroot as been allowed to invoke gnokii using sudo without password. This implies the following line in /etc/sudoers:

itroot ALL = NOPASSWD: /usr/bin/gnokii

More over, a log file has been created with write permission for itroot user: /var/log/SMS.log". This log file will allow you to make sure that gnokii is doing its job
