Hi,
a short follow up on my question.
I never looked into the root of the problem, so I don't know the answer to
my questions above. Never got any info from Telit either.
I have fixed this with a minor modification to the "Comm2IP" module. It now
searches for the "CMS ERROR" message in the modem response. If it finds it,
the PC will reboot (it fires the shutdown command). This has kept the
system running for weeks and it doesn't matter if the PC reboots in case of
modem errors.
Hope this can be helpful for someone.
Best regards
Brian
