AGU,

we will certainly not do all the work for you.

If you haven't got any code so far search the forum for "serial" and "EEPROM" and you will find tons of examples.

You have got to do your homework on your own.

If you already have some code, but having problems with that existing code post it and we will have a look at it.

...and you're going to have to be clever too...

9600 baud is approximately 1 character every millisecond (give or take)... it takes 10mS to do a serial EEPROM write...
