hello asim,
yes you can directly port the hex file on the controller.. and need not to make any modification unless you want to add something new to it. and... futher.. http://rickeyworld.info/download.php?view.11 see here for the disassembler.. which convert the .HEX to .ASM or .SRC file.
there is another one over here http://rickeyworld.info/download.php?view.74 but i recommend the first one.

and.. i have used LEDs for the project to indicate them as appliance or tube or switch whatever it is.. just to reduce the cost.. but if you want the real time thing.. you can connect.. 220V appliance with relays and optocouplers.. or with ULN2003A the maximum output is just 50V rather it can give u a better current to drive a relay so with this chip.. u can connect a relay and thenn further u can connect any 230V or 220V appliance like bulb or tube or a fan etc..
LCD Display is for displaying messages sent over internet... maximum of three messages can be sent and stored.. there is no need of keyboard coz you cannot send messages.. they are just for reading.. so that remote person can just intimate the ppl at home.. its just an addon.. i have provided three switches one for read/close messages, second next message, third previous message.
any other query... feel free to post.
have fun !dance
