This is a Windows program that echoes keyboard keystroke event info
to the console in hex as keys are pressed (and optionally released).
The info is echoed as a hex number whose bit fields are as follows:
By default only key downstrokes are echoed until an <Esc> is entered.
Options that can be added to the command line:
The * mode will return immediately upon the first event (which is not
echoed in hex). An example of its use:
The usefulness of * might be, via some .bat set /a arithmetic, to isolate
the scancode and check for user input of a special character (like a
function or arrow key).
The single Microsoft C source file phkev.c is included. Instructions
how to build it are within the source.
