i am trying to perform stepper motor interfacing with 8051 micro-controller.micro controller board-DYNA-51EB..Hex file is created in keil software.but using flash magic it is not able to transfer hex file in to micro-controller kit..and got error message :unable to communication(in use)ensure no other applications are using the com port.Tru raising or lowering baud rate.
Why do you think it necessary to write your entire post in BOLD??
And why start a new thread, instead of continuing in the one you had already:
http://www.keil.com/forum/62360
Have you done as I suggested there?
Note that FlashMagic is an independent, 3rd-party tool - it has nothing to do with Keil.
For FlashMagic support, go to:

is the chip Atmel or NXP?
