Dear friend there are a lot of errors in your code. First u set IE.4,3 and IE.7 (enable all) is clear. You don't need interrupts to transmit a byte at TX pin try this AND COMPARE IT WITH YOUR CODE

org 0000h
ljmp init
org 0100h
init: mov a,#33
MOV SCON,#50h ;mode 1
MOV TMOD,#20H ;timer1 in mode 2
MOV TH1,#0FDH
ORL PCON,#00H
SETB TR1
CLR TI
LOOP: MOV SBUF,A
JNB TI,$
CLR TI
SJMP LOOP
END


TH1={256-(Kxfosc)/(384xBAUD RATE)}
SMOD (PCON.7) =0 =>K=1
SMOD =1 => K=2
fosc =11.0592MHz
B.R=9600BPS

GOOD LUCK
B.X
