Cannot unlock device /dev/ttyS0

I am using Gnokii to send alert that is done through a Mobile phone connected to the Linux server through USB cable, and I used “port = /dev/ttyS0” under gnokii setting.

It work for some time and stops with showing below error message

[root@monitor#] gnokii --identify
GNOKII Version 0.6.19
Telephone interface init failed: Command timed out.
Quitting.
Cannot unlock device.
Command timed out.

to make this work again, server has to restart or disconnect and connect Nokia phone again

Do you know what does this error means, and how to solve?

this is really an argent matter.

thanks

Log file doesn't show any thing, after it crush, I will even double check that for you.
But dmesg shows this:

cdc_acm 4-2:1.1: ttyACM0: USB ACM device

After I restarted the server it works and i get following message from "gnokii --identify"
[root@monitor ~]# gnokii --identify

IMEI : 352042021632084

After an hour it will crash and the message mentioned earlier appear.

can you please explain to me what I need to do, I didn't understand:

You really need to increase logging so you can see what the USB device does. You could start by turning it on in your config above.
