hi i the project i awesome thanks for the share
and i have a doubt
from the video wat i learnt is that .... the circuit has been connected to the PC1 thought Haserver.exe thought a set of commands we are controlling the micro controller ...
is it possible to do the same... if we execute the Haserver in an other stand alone system PC2 with internet and control the micro controller which is been already connected to the PC1 over internet ???

no thats not possible. HAserver is a bridge between 8051 hardware and internet connected to PC1. If your PC1 is running HAserver and hardware is connected to PC1 then you can use any other pc which is connected over LAN/internet to connect PC1 and control its hardware.

thanks for the reply ..
so how do i connect the other pc to my PC1 ??? i mean should i run open a telnet from other pc and connect it to PC1 thought the net ??

yes right. open command prompt and type following commands:

telnet [ip] [port]

if default port (23) is used then no need to give port.

hi is it possible to run the some program in 89s52 micro controller... ????

I do not understand this statement. what kind of program? when you load your hex file on 8051 its nothing but a program.

sorry its not some program .. its same program
can i use the same HA.hex of 89c51 and burn it in 89s52 micro controller will it still work.??.
i came to know the only difference between them is the way the are programmed .. i.e c series are programmed through parallel programmer and s series are programmed though parallel or isp ports
but will the ha.hex work on both ??

telnet "ip address" 23
please clear my doubt -----here ip address means public IP of the computer where micro-controller hardware is connected..??
please reply..!!!
