Function 08h (8)         Console Character Input without Echo

Waits for a character from the standard input device. Does not echo,
but does check for Ctrl-Break and Ctrl-C.

On entry:      AH         08h

Returns:       AL         Character

                                                                          

This function waits for a character from the standard input device.
When the character is available, the function returns its ASCII value
in AL but does not echo it to the standard output device.

Notes:         A 0 returned in AL means that one of the "special"
characters (a function key or a cursor key, for
example) was input. Call the function again to read
the extended code of the special character (see the
Key codes table).

The only difference between this function and
Function 07h is that this function checks for Ctrl-
Break. If Ctrl-Break or Ctrl-C is input, this
function executes an INT 23h.
