Buffering of DATA?

Question

The low level serial driver makes no provision for buffering the received data.What is the meaning of this statement

Answer 1

It means the serial driver will only store the last 1 byte received. If another byte is received before you read out the previous one, then the previous one will be lost. In this situation you need to read the received data after every byte. I dont know what language or platform you are using, but you can set up a receive interrupt (best method) to get the data, or a timer and just check for receive data every so often.
