Configuring Kannel with GSM modem

These is sample config for Alcatel X200L(1bbb:0017) We assume that you have setup you modem(for example you have your modem at /dev/ttyUSB0-4)

1. Add kannel to dialout group (/etc/groups)
2. Config some stuff:
/etc/kannel/kannel.conf:

	group = core
	admin-port = 13000
	admin-password =
	admin-deny-ip = "*.*.*.*"
	admin-allow-ip = "127.0.0.1"
	smsbox-port = 13001
	log-file = "/var/log/kannel/bearerbox.log"
	#log-level = 3
	box-deny-ip = "*.*.*.*"
	box-allow-ip = "127.0.0.1"
	dlr-storage = mysql
	#--- mysql connection
	group = mysql-connection
	id = mydlr
	host = localhost
	username = kannel
	password = jMYnv29rcScJEZsM
	database = kannel
	max-connections = 1
	# ---- DLR table structure ----
	group = dlr-db
	id = mydlr
	table = dlr
	field-smsc = smsc
	field-timestamp = timestamp
	field-destination = destination
	field-source = source
	field-service = service
	field-url = url
	field-mask = mask
	field-status = status
	field-boxc-id = boxc_id
	# device conf
	group = smsc
	smsc = at
	smsc-id = usbmodem
	modemtype = auto
	device=/dev/ttyUSB3
	my-number = +359888123456
	log-level = 0
	group = sms-service
	keyword-regex = .*
	catch-all = yes
	max-messages = 0
	get-url = "http://localhost/api/receive.php?sender_gsm=%p&receiever_gsm=%P&text=%a&dlr=%d&s=%n"
	group = smsbox
	bearerbox-host = 127.0.0.1
	sendsms-port = 7048
	global-sender = "sms"
	#log-level = 3
	log-file = "/var/log/kannel/smsbox.log"
	group = sendsms-user
	username = senduser
	password = sendpass
	max-messages = 3
	concatenation = true
	include = "/etc/kannel/modems.conf"

/etc/kannel/modems.conf:

	group = modems
	id = generic
	name = "Generic Modem"
	speed = 9600
	init-string = "AT+CNMI=1,2,2,2,1"

Important params:

* device - You should find out on what device you can access the modem with AT commands. So we try all of them from 0 to 4. This device works with 3 and 4.

* init-string - this one is extremely important. If it is not correct you even may not connect to the modem, can't send a message or can't receive DLRs. If you get "got +CMT but pdu_extract failed" message when receive a DLR it is highly possible that the init-string is not the correct one for your device.
