I´ve been seeing some Keil examples and I can´t get the concept of serial input & output buffers. These examples aren´t fully documented...

I´ll apreciate any kind of info about this topic.

In my proyect I want to read the serial (GPS NMEA input) and store it in EEPROM of the AT89S8252, for later Tx through a GSM modem.

I´ll also apreciate any other info about writing & reading EEPROM.

Thanks!
