Hi again,
i'm little bit confused.

I use at89c51 with external RAM into which my main program should be loaded.

I found a bootstr.asm online to do that (bootstr will be stored in microcontrollers ROM)

; To use the bootstrap program, an Intel Hex file is sent through the serial
; port in 8–N–1 format at 9600 baud.

-------------
main question
-------------
how should i send it?
should the program(soft) that sends hex file be specific?
i understood that hyperterminal is improper.
So what should i use than?

help,
Tom
