nap() is an undocumented call invoked by the Xenix terminfo version's
getch() function--it is accessed by linking with the Xenix library "x"
(ie add "-lx" to the cc command line before -ltermlib).  BTW, you
may well experience problems using SCO's getch() call--it has a nasty
habit of returning null when the 'D' (or is it 'd'?)  and 'P' keys are
pressed.

Good luck.
