How to full reset the module

We have a development board with a WISMO228 module. To be shure in the
application we reset the modem in the beginning and after power cycling.
But many commands (like PSFS) are not reset by AT&F nor by ATZ not even
powercycling is enough. So i wonder if there is no way to fully reset the
module by a command.


I don’t think AT&F and ATZ commands would have an effect on PSFS indications.As i see from the command guide , the *PSFSNT command is not listed in the "parameter impacted by &F command ". Can you please explain in brief why you want to disable the indication.
