[BusyBox] Serial port

Hi all,

I'm currently trying to put getty from busybox on the serial port of my
embedded PC.

I succeed on COM1 and COM2; but in order to run it from COM3 and COM4
I need to initialise these ports during the kernel boot.

To do that, I need to run the following code
ComAddr[0] = 0;
ComAddr[1] = 0x3F8;
ComAddr[2] = 0x3E8;
ComAddr[3] = 0x2E8;
ComAddr[8] = ((ComAddr[8] & 0xF1FF) | 0x0600);	

Does anyone could explain where I need to launch that code?
And how to compile it (normal gcc, static?)

Thanks
Patrick.
