cf_ta    -  Standard  font selection structure. Can be  NULLed if no custom
            font  is necessary. If font cannot  be located then the default
            one will be used.

cf_cs    -  Pointer  that takes  ColorSpec table so  that new colors can be
            set for this screen. Can be NULL if standard colors are fine.

cf_drimap
         -  Pen  mapping table aka DrawInfo. This  table consists of UWORDs
            that are  ~0 terminated. Each entry  defines logical pen number
            used for  rendering OS  related elements. Set to  NULL if it is
            OK to use default mappings.

cf_lfirst
         -  If  this  is  set  to something above  0 then the  very first n
            colors will be locked.

cf_llast -  If  this  is set to  value  above 0 then  last n colors will be
            locked counting from last color in 8 bit notation.

cf_modeid
         -  Standard  modeid  value  that selects the monitor/graphics chip
            used to handle the screen.

cf_depth -  Color  depth  of the  screen  to be opened. This  value  should
            really  be  always  truncated  to something like 8 even for RGB
            screenmodes. Well accepted values start from 1 to 8.

cf_handler
         -  Console  handler name  and/or its arguments. By default this is
            'CON:'. Can be NULL if no special wishes.

cf_title -  Name of the  public screen for visibility. NULL terminated text
            in here. You can pass NULL too so that cf_pubname will be used.

cf_pubname
         -  Name  of the public  screen for unique marking. If this is NULL
            then unique screen number will be used instead in hex notation.

cf_backpen
         -  Pen number to be used as a background color before any windows.

cf_ibgpen
         -  Pen number to be used for background of the OSD facility.

cf_ifgpen
         -  Pen number to be used for foreground of the OSD facility.

cf_active
         -  Which  window should be active by default? Possible choices are
            0 to 3. Everything outsize this range has no effect.

cf_numcon
         -  How many shells should there be on the screen? Possible choices
            are 1 to 4. 0 means 1. Note, it is not enough just to state the
            amount of windows, you still need to call rearranger function!

cf_commo -  This member is boolean and allows to activate Commodore 64 look
            and feel.

cf_behind
         -  Should the screen be opened behind all other screens? Member is
            boolean.
