Sorry i didnt placed comments on my code but now they are

The main program which gave me the basic idea of trasmitting data to the pc serially is

ORG 000H
        JMP     MAIN
ORG 023H
        JMP     SERIAL ; label where to jump to transmit the next bit
ORG 030H
MAIN:
        MOV     SCON,#50H
        MOV     TMOD,#20H
        MOV     TH1,#-24
        SETB    TR1
        SETB    EA
        SETB    ES
        MOV     A,#'A'  ; moving the intial ASCII code after which increament will take place of this intial value
        MOV     SBUF,A ; as this ASCII code is now present in A, moving it in the Serial Buffer
        JMP     $ ; waiting for the interupt to occour

SERIAL:
        CLR     TI ; when jumped to the label after the interpt, clearing the flag
        INC     A  ; increamented it to get the next ASCII code
        CJNE    A,#'Z'+1,SKIP ; deciding whether the last code has arrived 
        MOV     A,#'A' ; if it is arrived than moving the initial code again
SKIP:
        MOV     SBUF,A
RETI

END
