Hi, I'm trying to send some data to arduino using cmd(windows command prompt), but the
board(arduino) seems not to receive any data. I tryied with hyperterminal and serial monitor(in arduino IDE) and it worked,
but with cmd, not even a blink from TX/RX LEDs on the board.
Here is an image with my configuration, and yes arduino is on port 15 
I'm using win7, on my friend's old XP it worked like a charm.
Nice!
Try putty, this software is higly configurable and works really well.
I use it to monitor serial data as well.
Will try putty, but I would prefer cmd because I could write .bat scripts which could be executed.
There are some issues with some software and COM port numbers greater than 9. There is some convoluted way you need to reference them. Something involving dots and slashes, but I don't remember the details, because I don't have any bluetooth crap attached to my computer that forces it to use so many COM ports. Search the forum or microslop's site.
Putty can do that to!
It is in the putty application suite, it is called "plink" and it is free.

Thanx, I changed port to COM2 and now it works.
