#109544 - storing serial data in memory
In my proyect I want to read the serial (GPS NMEA input) and store it memory, for later Tx it through a GSM modem as GPRS packets.

I thought of storing data in the AT89S8252 2K onboard EEPROM but I recieved some complaints about it.

Whats wrong on storing in EEPROM?
In this project Responce time is note crucial.
I though of using EEPROM because of the 2K capacity.

I´m still looking for the data capacity of the GPRS packets
as soon as I find it out, I´ll post it here.
