First, in both codes you will need at least this line:
so the main program executes this loop endlessly and is only interrupted by arriving of a serial character..
What I don't understand is how are you going to call TRANS interrupt?
You will nee to use INT0, or any other pin (for example P1.0 ..) to execute TR

In my design I have a free 8051's port-1. It's a bit-addressable ll'l port. I have a iPAQ HHT with serial interface. But my txd and RxD of 8051 (UART) are used for prog and debugging. How can I interface my iPAQ?
Is serial to ll'l convertor is the only solution?
Please suggest your ideas...
Thanks in advance,

which type of bt you want to interface.
A ready made bt which has serial interface is well suitable for you.
which has both txd and rxd unit.

it is the serial data buffer.
when you want to transmit in serial mode write 8bit data here.
it will get transmitted serially in txd.
when 8051 receives serial data in Rxd , it assembles and put the 8bit data here for reading.

i differ from kandhu in this answer...
The moment a byte is written into SBUF, it is framed with the start and stop bits and transferred serially via the txd line...
SBUF is 8 bit register, so how and where is the data framed and where is it stored? and from where is framed data transmitted.....

Hi your are trying to establish serial communicaiton using IR modules, for this the above circuit is not appropriate. you should make some changes on that circuit
do one thing remove the first 555timer(left side) and connect the txd pin of the 8051 to 4th pin of the second 555timer. Because the second (right side) 555timer is for to generate 38Khz
