henry,

i hv set d baud rate according to datasheet

MOV DPTR,#_LCR ;LOAD LCR
MOV A,#80H ;LCR= 1000 0000B = 80H
MOVX @DPTR,A ;ENABLE BAUD RATE GENERATOR DIVIDER LATCH
MOV DPTR,#_DLM ;LOAD DLM
MOV A,#00H
MOVX @DPTR,A
MOV DPTR,#_DLL ;LOAD DLL
MOV A,#48H
MOVX @DPTR,A ;BAUD RATE = 9600 for 11.0592Mhz OSC: 11.0592M/(16*9600)= 48H
MOV DPTR,#_LCR ;LOAD LCR
MOV A,#03H
MOVX @DPTR,A ;8-BIT,NON-PARITY,1 STOP BIT,DISABLE DIVISOR ACCESS LATCH
