Serial port (COM1) and fileio?

Hi all,

is there some way to do a call similar to
    fd = open("COM1:", O_RDONLY);
to access the serial communications port driver? Setting baud rate?

Maybe this is a newbie's question... however, i didn't find any hint till now. 
I remember 
from my good old CPM-days one had to fiddle a bit inside libc.

Any help is highly appreciated. Thank you.
