In (MSDOS - Turbo C++ ) based programs port number 0x60 can be used
for detecting key presses, for example 0x1E and 0x9E for 'A' ; 0x1F and 0x9F
for 'S'. (0x1E and 0x1F indicate that the corresponding key is down,
0x9E and 0x9F indicate that the corresponding key  is up.)

I'm looking for the same in BCB. I know that there are OnKeyDown and OnKeyUp
events. If I supply OnKeyDown and OnKeyUp events for Form1 and if Form1 is
empty the OnkeyDown and OnKeyUp for Form1 event handlers execute, but if I
place anything on Form1, for example a button, the OnkeyDown and OnKeyUp
event handlers for Form1 don't execute.

So, there should be some Win32API for handling key presses, what are the
related functions?. It's enough for me to detect that an arbitrary key is
down or up as port number 0x60 in MSDOS.
Thanks...
