PPPD: Failed to open /dev/modem_at0: Input/output error

[Herraiz Stéphane]

Hi,
We made a CRON task to test and reboot modem connexion to internet:

#!/bin/bash
PATH=/bin:/usr/bin:/sbin:/usr/sbin:/etc/init.d
PPP=/etc/init.d/ppp
wget -q --spider http://google.com
if [ $? -eq 0 ]; then
    logger -t NOMAD "Internet test ok"
else
    mts-io-sysfs store led-sdk-c 0
    logger -t NOMAD "Internet lost -> reseting ppp connexion"
    if pidof pppd
    then
        killall pppd
    fi
    sleep 10
    $PPP start
     logger -t NOMAD "ppp connexion (re)started"
fi

But sometimes we have this message in the logs:
pppd[25168]: Failed to open /dev/modem_at0: Input/output error
and the internet connexion never comes back.

Is my script is ok?
While to detect such error in my script and how to repair the modem connexion?

Thanks
