I am using one of Gumstix Overo boards, it has OMAP3 CPU, which includes some UARTs.

Now, I am wondering what will happen if I will be sending some data on some serial port (for example /dev/ttyO0), and during that time, I will use stty command to change port settings, for example speed?

Is it possible to do such thing or should I firstly, stop using serial port, change settings and then start using it again?

There will be some data loss in your case ,So It is advisable to stop using serial port then change serial port settings and start using it again.
