01 Nov 2004 19:36 Help in downloading firmware via Hyperterminal. (Bootloader)

Hi Everyone,
I'm a rookie in microcontrollers.
I have the bootloader files that come with CCS compiler. I need to be able to upload a .hex file (using C to code) unto the micro via hyperterminal. I do not know how to have the bootloader code on one part of the micro's memory and have the application firmware on the other part. The firmware uses hyperterminal. I want to be able to interrupt its normal operation by pressing some sequence of code and then go into service mode where I can upload new firmware. Can someone please point me in the right direction?
Thanks a bunch!

thanks for the quick reply, but it is "required" to use hyperterminal. The firmware uses hyperterminal and so "higher authority" wishes that everything happen within that. I tried that website but its given in assembly code. I'm using C code and actually im not strong with assembly.
thanks
