   My simple OS uses int 0x10 to display o/p. I'm adding a routine (txt)   
   that is a simple text editor which writes to memory at segment 0xb800. I   
   enter/exit the txt routine using call/ret.  Once I have filled the   
   screen with text using the txt routine and then ret back to the OS loop   
   subsequent int 0x10 o/p  does not get shown on the screen.  Even when   
   the cursor is repositioned to row/col 0/0.  How do I get int 0x10   
   display capability back after filling the screen using memory at 0xb800?   
   TIA.  Bill S.
