Change serial line baudrate in FF5.0 on ATmega?

[Jindrich Vavruska]

Hello, I burnt the ready-made FF5 into ATmega328 (Arduino Nano). Unfortunately, 9600 Bd seems to be rather slow. Is there a way to change the baudrate through an EEPROM variable or something like that? i.e. without recompiling and re-burning the whole stuff...

Note that in order to disable any faulty turnkey word you need to have a usable UART connection during the first 2 seconds of the restart.
I order to disable the turnkey you need to start the terminal program with 9600 baud and press the escape before the turnkey word executes.
