#96192 - double function of SBUF
Responding to: ???'s previous message
Rahil Aslam said:
3)As i receive the data in SBUF and then bring it ACCUMULATOR, then if i want to send the same data to serial, what should i do.

There are in fact two registers at the same SBUF address: if you write, you write into the buffer of transmitter, if you read, you read the buffer of receiver.

So you receive your data and read into accumulator
   mov  a,SBUF
you can echo it back simply by
   mov  SBUF,a
