ttySAC2 is not there

Hi guys ttSAC2 is not in /dev/ do you know where in the kernel can I find
the configurations for it?

Your question implies ttySAC0 and ttySAC1 do exist?

If no:
Device Drivers  --->
   Character devices  --->
     Serial drivers  --->
        <*> Samsung SoC serial support

If yes:
Adapt the platform file and register the third UART.

thank you for replying Juergen,
When you say "Adapt the platform file" which file I need to modified?

You must adapt the file which is used and compiled for your target.

Hey Juergen, I did a full search on kernel 2.6.32.2 and for ttySAC2 and is
not be found in any of the files. how is that possible?

In a recent kernel these UARTs are registered in
arch/arm/plat-samung/init.c -> s3c_arch_init(). I don't know where in such
an old kernel like the 2.6.32.2 is. Maybe in
"arch/arm/mach-s3c24xx/mach-mini2440.c"
