   In warp 3 and warp 4 beyond FP 6, the call is AX = 1680h Int = 
   2fh. Note that the call was broken in the warp 4 GA version up 
   till FP 6 was released. You can also use the slightly less 
   effecient DOS IDLE Int = 28h.

   I have a pascal unit that encapsulates all this and a lot more, 
   such as OS detection, for every Intel based OS, drop an email to 
   leea@psynet.net if you want a copy.
