Use friendlyARM to make GUI and using USART to transfer data

Hello everybody. I want to use the FriendlyARM kit to transfer the number 
I had choosen on the screen ( using touch screen) to another MCU ( eg: ARM
M3). But I got into trouble because I don't know how can I do it. My
Friendly ARM kit not found termios.h on ls/dev so I can solve my problem.
Can you give me some advices. Thanks!

You won't find termios.h listed in /dev

Qt would be your easiest approach for a GUI, search "mini2440vietnam"  he
has lots of good tutorials on his site.  You probably could even use Qtopia
2.2 already on the DVD and your target. There are heaps of tutorials out
there.

Good luck!
