Problem on serial ports with modem SMSC

[Stefano Baronio]

 Hello, everybody,
 I installed kannel 1.0.3 (only sms gateway) and it works fine at the
first
 start, but after I stopped it with the start_stop_daemon utility, it
 doesn't run anymore. It can't see the modem no more.
 The command I launched to stop it is "start-stop-daemon -k -x
 bearerbox-1.0.3", the smsbox quit itself after this.
 I can't connect to the modem no more.
 Does anyone has any idea ?
 Thanks
