Function  0Ah   Buffered Keyboard Input 
      Reads characters from STDIN and places them in the buffer beginning 
      at the third byte. 
entry   AH      0Ah 
	DS:DX   pointer to an input buffer 
return  none 
note 1) Min buffer size = 1, max = 255 
     2) Char is checked for ctrl-C. If ctrl-C is detected, executes int 23h. 
     3) Format of buffer DX: 
	byte       contents 
	 1      Maximum number of chars the buffer will take, including CR. 
		Reading STDIN and filling the buffer continues until a carriage 
		return (Enter or 0Dh) is read. If the buffer fills to one less 
		than the maximum number the buffer can hold, each additional  
		number read is ignored and ASCII 7 (BEL) is output to the  
		display until a carriage return is read. (you must set this 
		value) 
	 2      Actual number of characters received, excluding the carriage 
		return, which is always the last character. (the function sets 
		this value) 
	 3-n    Characters received are placed into the buffer starting here. 
		Buffer must be at least as long as the number in byte 1. 
     4) Input is redirectable. If redirected, there is no way to check EOF. 
     5) The string may be edited with the standard DOS editing commands as it 
	is being entered. 
     6) Extended ASCII characters are stored as 2 bytes, the first byte being  
	zero.
