Comm ports on Pc386

[Fernando RUIZ CASAS (E-mail)]

Hi
If you want to use shell_init without tpc/ip enabled I can send to you
the patch already submitted to Joel.(05/26/01)

I have not made none modification in the pc386 BSP code to enable
the ports. Only this code has been used.
In shell_init only a make raw mode TERMIOS is done
(How the linux man page says)
None error is showed in the compilation of pc386(pc686) bsp.

Browse in the sources and ask directely to Eric, Rosimildo & more about the
use of this. (The authors of little patchs...)
I have use this ports like a linux device using only TERMIOS programming.

And this works successfully.

Your code seems correct. I Can try it.
