Sometimes my modem gets offline by accident and reconnected to the host, but gammu-smsd cannot get recovered and keep outputting error logs:

Mon 2023/12/11 21:25:31 gammu-smsd[192100]: Error getting SMS status: Error writing to the device. (DEVICEWRITEERROR[11])Mon 2023/12/11 21:25:46 gammu-smsd[192100]: Error getting SMS status: Error writing to the device. (DEVICEWRITEERROR[11])......

Here's the command what I was running:

/usr/bin/gammu-smsd --config=/usr/local/etc/gammu/smsd.conf --pid=/run/gammu-smsd.pid --max-failures=3 --daemon

The config parameter--max-failures seems take no effect here, and I don't know if there's any configurable item for the program to detect this kind of error and terminate or restart (daemon mode) itself. Only restart manually can solve this.
