ECHO Return the status of the CapsLock, NumLock and ScrollLock keys
ECHO Notes: The status of either the requested or all key lock(s) is displayed
ECHO NumLock and ScrollLock. The value of the environment variable
ECHO KeyLocks, which will also be returned as an "errorlevel", will
ECHO either be the status of the requested key lock (0=OFF, 1=ON) or
ECHO a combination of the three (C=64, N=32, S=16).
ECHO This batch file uses DEBUG to read the keyboard status.
