What program is running on the 8051 side to send the data? What baud rate is it using? Is it configured for flow control? If the 8051 side is sending repeatedly, is it sending some kind of "frame" that can be unambiguously recognized so as to be able to tell the difference between starting reception in the middle of a sample vs the beginning of a sample?
Just storing samples as they come in is usually the relatively easy point if they will all fit in memory. If they do not all fit in to memory; if they do not all fit in to memory, buffering can be a problem.
