我注意到我在 Ubuntu 上运行的 gammu-smsd 守护程序突然不发送消息（我的 postgresql 数据库的 sentitems 表未更新）。首先，我注意到守护程序没有运行，因此我重新启动了它：
$ sudo /etc/init.d/gammu-smsd start
* Starting Gammu SMS Daemon gammu-smsd [ OK ]
然后我检查了系统日志（这是我配置 gammu-smsd 报告的日志）：

这是否意味着插入计算机串行端口的调制解调器没有响应？（我通过 ssh 访问机器，如果没有必要，我不想亲自去计算机。）
但请注意，我可以运行sudo minicom并获得以下内容：
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 不允许我在窗口中输入任何 at 命令。它只显示一个闪烁的光标。虽然我可以使用CTRL-A Z和其他CTRL-A快捷方式访问菜单，但我无法在窗口中输入任何 at 命令。
minicom 日志如下所示：
$ cat minicom.log

知道为什么短信没有被发送吗？

请使用当前用户运行 gammu-config 并..
编辑/etc/init.d/gammu-smsd
# user which will run this daemon
USER=USERNAME
例如
USER=apis17
默认用户是 gammu，文件夹中没有.gammurc文件/home/gammu
