I have a Quectel L80 Module earlier set to 4800 Bd. It have worked stable with this baudrate over years. Now I want to change it back to 9600 Bd. I use the command “$PMTK251,9600*17” with CR-LF on end. To send it I use the terminal program Hterm. The command make the L80 working with 9600 Bd - all seems o.k. But if I switch the power off the L80 and switch on the baudrate is 4800 Bd again. The L80 seems to guess the 9600 Bd change if power off. What I have to do to get the 9600 Bd stable after switch off and on the power.
Thank you very mutch for help.

Now I have found the solution - this (new) command set the Baudrate durable:
But the command $PMTK314,0,1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0*29
is not durable too. Is there a similar command which durable saves the output only for RMC?
