thats really a strange problem. Well debugging this ip little difficult but if you con do it will be good for you. After command and data is extracted, display it on hyper terminal you need to make changes in program to display the values on pc. Thats the only way to check whats the real problem. You need to tell me what you get when you press 123 on remote.

sunrom i know which project you are talkin about, but what we are talkin here is debugging your problem so the only way to debug it is.. to find out the o/p you are getting from IR receiver. To check that o/p we need to display it somewhere so serial can be one way.. second could be LCD, third is LED on a port so whichever you feel better you can chose.

serial circuit is already there.. all you need to do is simply extract the three important things, address, command and flip bit and display it.. and check it on serial window after you press the button, so you can check whether you are getting the right value or not.

Dear Ajay, My hand is really tight in assembly as I am an IT pro, and the code attached with the project is written in Assembly. Can you please do me one favor, either rewrite the code in C or add few procedures in the existing assembly code to display the address, command and flip to the attached 2 line LCD terminal.

Hope it won't be that difficult for you
