C8051F120 extended Hex record

Hi ,

I am using C8051F120 mcu for my application software. This software has 3 hex files because in this i have used code banking. I have use Bank 0,1,2,3. Now I am using JTAG for downloading code.

Now I want to write code for boot loader for this MCU. So I have some queries to implement it.

1.When I have created bank setting in Keil project then 3 files created those not .hex. Those are .HO1,.HO2,.HO3.
2. While downloading code through there is option to select bank number.
3. Now I want to download code through hyper terminal.

My quesions are
1. How can I give this bank selection through hyper terminal because in datasheet exact address mapping not given for each bank ?
2. There is setting in keil for extended hex record how it can set and use in code?

Please reply asap.

Regards ,
Prashant.
