gammu-smsd守护进程不发送短信

我注意到在Ubuntu上运行的gammu-smsd守护进程突然没有发送消息（我的postgresql数据库的sentitems表没有被更新）。 首先，我注意到damemon没有运行，所以我重新启动它：

$ sudo /etc/init.d/gammu-smsd start * Starting Gammu SMS Daemon gammu-smsd [ OK ] 

然后我检查了系统日志（这是我configurationgammu-smsd报告的日志）：

这是否意味着插入计算机串口的调制解调器没有响应？ （我通过ssh访问机器，如果不需要，我不想实际上去电脑。）

请注意，虽然我可以运行sudo minicom并得到以下内容：

 Welcome to minicom 2.4 OPTIONS: I18n Compiled on Jan 25 2010, 07:02:36. Port /dev/ttyS0 Press CTRL-A Z for help on special keys 

但是，minicom不允许我在窗口中input任何命令。 它只是显示一个闪烁的光标。 虽然我能够使用CTRL – A Z和其他CTRL – 访问菜单的快捷方式，但我无法在窗口中键入任何命令。

minicom日志看起来像这样：

 $ cat minicom.log 20130610 17:57:50 Hangup (0:10:29) 20130611 10:47:56 Gone offline (0:00:02) 20130611 10:53:59 Hangup (0:00:00) 20130611 12:51:50 Hangup (0:00:00) 20130612 00:43:39 Hangup (0:00:00) 20130616 21:45:54 Hangup (0:00:07) 20130624 14:22:48 Hangup (0:01:43) 20130624 14:26:02 Hangup (0:02:58) 20130624 16:58:52 Hangup (2:19:25) 20130625 15:04:39 Hangup (0:03:54) 20130626 10:43:19 Hangup (0:08:13) 20130627 15:46:02 Hangup (0:00:35) 

任何想法为什么短信不被发送？
