DS89C430 - ISP programming - cannot connect to loader

I have downloaded the required softwares from Index of **broken link removed**
Then I opened the serial port successfully.. (USB to SERIAL converter, that is 100% working)
After that when I try to connect to loader, I am getting error...
I grounded the EA and PSEN and provided 5V to RST...
But, I am sure it is communicating with the serial port but still showing error as below:
**broken link removed**

Then I simply tried to connect by giving 0v at RST (I know it will not work, but just to know the response I did this)
Then the result is as below:

**broken link removed**

So, I think it is getting some required response in the first case but I couldn't understand why it couldn't connect to loader...

Any suggestions?

looks like communication error.
1. double check the bitrate and configurations of the com port.
2. check whether the clock to the MC is good.
3. use a computer that have the com port directly in it.
4. double check the connection wires.
