+/*
+ * conio.h
+ *
+ * Ullrich von Bassewitz, 06.08.1998
+ *
+ *
+ * This is the direct console interface for cc65. I do not like the function
+ * names very much, but the first version started as a rewrite of Borlands
+ * conio, and, even if the interface has changed, the names did not.
+ *
+ * The interface does direct screen I/O, so it is fast enough for most
+ * programs. I did not implement text windows, since many applications do
+ * not need them and should not pay for the additional overhead. It should
+ * be easy to add text windows on a higher level if needed,
+ *
+ * Most routines do not check the parameters. This may be unfortunate but is
+ * also related to speed. The coordinates are always 0/0 based.
+ *
