problem to communicate with Hyperterminal

Hello,

I'm a newbie in ARM and in Keil Microvision IDE. I downloaded an example from st site, which allows to communicate via serial port with an hyperterminal.
I compile then download the program in the ARM7. When I am in debugging mode, I can see the program works properly thanks to serial window inside Microvision.
But When I want to use hyperterminal on my PC to communicate with STR7, nothing happens...I take care of using correct settings for serial comm, same settings than in STR7.

Could you help me please?

    If I understand it right the PC talks with the board very well by using Keil's µV.

    Only Hyperterm won't work.
    I have had the same with LPC21xx-Board and found out the DTR line, which cause a RESET on the board, was wrong driven from hyperterm.
    A switch to disconnect the DTR at the sub works fine.

    Check it out.
