if you send four bytes:
 $86,$87,a,$00
over the link, a will be put into _kbdkey ($c005) and bit 7 at (iy+$15)
will be set
if you send
 $86,$87,a,b
where b isn't 0, b will be put into _kbdkey and a will be put into
_keyextend.
this is done in the silent link routine.  every time i've tried this, it
just crashed the calc.
oh, an acknowledge is sent back, too.
