Hi all,

HAPPY BIRTHDAY 8052.COM...

This question_bank is back with his next question...a serial communications problem...
For a start, I entered "Serial Communication" in the forum search and it returned me 538 links. I tried a few of them though (as many as 15-20)but none were rewarding... So, I decided to hit the question straight...
I wrote a program that just sends about 32bytes of data (Nothing else) as soon as it is started. This is the only program loaded in thechip.Kindly suggest where I am wrong. I connected the system to a PC and ran Hyper Terminal to capture the output but it remains blank for as long as I switch it on

Here is the code.. (written in 8051 IDE from ACEBUS).

Code:
==========================================
DB COUNTER
THVAL EQU 0FDH
ORG 0000H
AJMP 0100H
ORG 0023H
JBC TI,TMT
RETI
TMT:

AJMP R

MOV SBUF,A
