+*_initcon.c - direct console I/O initialization and termination for Win32
+*
+*	Copyright (c) 1991, Microsoft Corporation. All rights reserved.
+*
+*Purpose:
+*	Defines _initcon() and _termcon() routines.
+*
+*	NOTE: The _initcon() and _termcon() routines are called indirectly
+*	by the startup and termination code, thru the pointers _pinitcon
+*	and _ptermcon.
+*
+*Revision History:
+*	07-26-91  GJF	Module created. Based on the original code by Stevewo
+*			(which was distributed across several sources).
