Thanks for your quick answer.
Yes, I am familiar with WinSCP. But how can I prevent that modem settings or SIM card settings are overwritten and no longer working on Device 2?
The receiver of my configuration is sitting in another country and it makes everything complicated, if even the connectivity will no longer be possible with overwritten SIM / Modem settings.
Can we exclude those files? - Please name the modem relevant files, which should not be overwritten.
