 		 #125401 - large amounts of serial data
I am interfacing an external modem with the AT89C52, the modem is supposed to send 2KB of data whenever I signal it. ALL 2KB of data arrives serially at 9600bps whenever I send the signal.

My question is how can the AT98C52 process such large amounts of Data since it only has 256bytes of RAM. What should be the buffer size in serial communication? and where should I store the 2KB of data once it arrives? Can I use the onboard 8K flash to store it?

Any suggestions are welcome
