Thanks both
but Gary when you say POSIX compatible termios what does refer to? For example, if i want to configure the USART to operate with 9600 baud rate, what functions and where and how can i do that? I have seen software API to do that in the Atmel web site. Where is this POSIX software?Any example?
Sorry maybe i am a bit lost on this
Thanks in advance
