------------------------------------------------------------------------------

 * CHKANSI detects the presence of ANSI.SYS by using the function ChkAnsiCPR.
 *
 * Usage (from the DOS prompt): CHKANSI [>nul]
 * Example: see ANSIPRMT.BAT
 *
 * Exit codes:   0 = ANSI.SYS not detected
 *               1 = ANSI.SYS detected
 *             ( 2 = unknown, unable to open SCREEN for write )
 *             ( 3 = unknown, unable to open KEYBOARD for read )
 *             ( 4 = unknown, unable to read KEYBOARD )
 * Check these with ERRORLEVEL from DOS.
 *
 * Side effect: clearing of keyboard buffer (necessary, see comments in sources)
