First of all, I don't have another phone to try

I have succesfully sent SMS from the same phone but on Windows XP and latest Cygwin.
The config file is the default one, only the /dev/com4(on XP) changed to /dev/ttyS0(on Debian)
After I start the process with /etc/init.d/sms3 start I get this log file:
2011-09-16 08:24:02,2, smsd: Smsd v3.1.14 started. 2011-09-16 08:24:02,2, smsd: Running as root:root. 2011-09-16 08:24:02,7, smsd: Running startup_check (shell): /var/spool/sms/incoming/smsd_script.NxR1Pl /tmp/smsd_data.ICM0Xz 2011-09-16 08:24:02,7, smsd: Done: startup_check (shell), execution time 0 sec., status: 0 (0) 2011-09-16 08:24:02,4, smsd: File mode creation mask: 022 (0644, rw-r--r--). 2011-09-16 08:24:02,5, smsd: Outgoing file checker has started. PID: 16902. 2011-09-16 08:24:02,7, smsd: All PID's: 16902,16904 2011-09-16 08:24:02,5, GSM1: Modem handler 0 has started. PID: 16904. Will only send messages. 2011-09-16 08:24:02,6, GSM1: Checking if modem is ready 2011-09-16 08:24:02,7, GSM1: -> AT

And it stays like this.

If I use sendsms I get this:
2011-09-16 08:25:13,5, smsd: Moved file /var/spool/sms/outgoing/send_s4QNHO to /var/spool/sms/checked 2011-09-16 08:25:13,7, GSM1: Command is sent, waiting for the answer 2011-09-16 08:25:18,7, GSM1: put_command expected (OK)|(ERROR), timeout occurred. 1. 2011-09-16 08:25:18,7, GSM1: <- 2011-09-16 08:25:19,7, GSM1: ->

And I don't receive the SMS

I have tried to change to "/dev/ttyUSB0" and "/dev/ttyS1" but I get the "unknown device" error.
Any ideas?

Thanks.
Vlad.

I have fixed the problem with the help of some friend

Here is the conf file:
devices = GSM1 logfile = /var/log/smsd.log loglevel = 7 [GSM1] device = /dev/ttyACM0 pre_init=no init=ATZ init2=ATE0 memory_start = 1 mode = new baudrate = 19200 rtscts = yes report = no #pin = 1111

I have discovered the port using "dmesg |grep tty".
And I needed to change the USB port of the server and the connection mode from phone(to pc suite).
I think the problem was from the USB port.
Now it's working like a charm.
