Modem reset in mPLS62-w?

[Giacinto Cifelli]

Hi Aleksander,

the classic:
    AT+CFUN=1,1

the question, however, would be why do you want to reboot the modem?
It looks like you want to update the FW, but Thales offers its own
method, and so not what is delivered by the chipset manufacturer.

Cheers,
Giacinto
