I cannot reproduce this: your program works for me (after I fill in
some missing stuff to make it compile).

Note that that's 10 and 11 in hex, not in decimal.

Because it doesn't remove the key from the keyboard queue, as
documented in the library reference.

bioskey is a direct interface to the BIOS functions, so it returns the
scan code and the ASCII character as the BIOS returns them.  You can
use keys.h for keys without Ctrl/Alt/Shift modifiers.
