Re: atmel at89sxx isp flash programmer

Hi,
I tried using the ISP programmer mentioned in the above link with correct serial port number, I am getting the unable to connect to the serial port error message. When tried using the hyperterminal for sending the commands I am able to get the response echo from the microcontroller and I can see the status LED blinking whenever some character is typed on the hyperterminal. Is there any issue in using USB-to-RS232 converter with this ISP programmer software. Can someone provide me the source code of the ISP programmer.
Thanks,
Koteswara
