Sorry Magnus, I do not understand.
I have ttySC0 as default console and the system works; now I'm writing my
application for managing teh ttySC1 port for my specif problem.
Where can I find the PFC initialization for ttySC0 Port into the kernel tree?
Thanks a lot

If the boot loader usually sets up the pinmux and if the kernel does
not touch it then it will work. On SH the proper way to do this is to
let the kernel use the GPIO framework to configure the pinmux using
request_irq().

Have a look at this:
damm@t400s ~/git/linux-2.6 $ find arch/sh | xargs grep gpio_request | grep SCIF

err, it's supposed to be request_gpio(). =)

My problem is in
tcsetattr(HPort, /*TCSAFLUSH*/TCSANOW, &term)
Where can I find a term setting working a a very basic raw mode (just like the
ttySC0 running the terminal console)
Thanks.
