C.8 $PNMRX111, Software reset
This message is used to reset the systems. If the message is sent without parameters the receiver reboots
according to the fix procedure (hot, warm or cold) configured with the PNMRX101 or PNMRX104 messages.
A second parameter can optionally be used to specify which actions are executed after the reset. If the last
bit field is set to ‘1’, then the actions are repeated permanently at each reset, until this bit is cleared.
