Yeah, i make a mistake with the question, i get 8 bits and i whant to convert that 8 bit number in 2 bytes decimal.

if i get 1000000 i whant to send to the serial port 64 rigth now if i send the value to the serial port i recive a @.

rigth now i'm doing this


byte_to_bcd:
MOV R0,A
ANL A,#0Fh
ADD A,#0F6h
JNC byte_to_bcd_2
ADD A,#07h
byte_to_bcd_2:
ADD A,#3Ah
XCH A,R0
SWAP A
ANL A,#0Fh
ADD A,#0F6h
JNC byte_to_bcd_3
ADD A,#07h
byte_to_bcd_3:
ADD A,#3Ah
RET

if the value is 01000011 i get 2 bytes 43 that is the Hex value of the char C and i whant to get 2 bytes in decimal 67.
