Hello,
my external modem (/dev/ttyS0) Cinterion MC55i cannot send text/SMS anymore.
When I do a media test from Zabbix:
Media type test failed
/dev/ttyS0
Expected [+CMGS: ] received [ +CMS ERROR: unknown error ]
Provider simcard is oke and active.
It has always worked fine, until now....
Zabbix version 4.2.7 (CentOS7)
