Two questions - gotoxy() and unbuffered input

[latte]

Hi all -
  Just two questions about HLA.  ( Btw, I'm running Linux. )   
a) Does it have a gotoxy() function to go to a particular point on the screen? 
b) Does it have unbuffered input?  By that, I mean the ability to immediately capture a keypress without it displaying on the screen or having to press Enter.  Very handy for capturing arrow keys.   
  The reason I ask these questions is that I'm looking at doing a simple graphical boot-menu.  The first part of the boot process (of course) can't use HLA as it needs to be 16-bit.  However, I think it should be possible to use HLA at the "second stage" part of booting.     
  Many thanks in advance..... bye for now -
