Read character from keyboard

I managed to get it working on Windows 2000 by using the GetAsyncKeyState
function from user32.lib. When you read the documentation (win32api.hlp)
you’ll find out that you have to reset it first. So:

get the fct from the lib

GetAsyncKeyState = Win32API.new(“user32”,“GetAsyncKeyState”,[‘i’],‘i’)

reset the state for the ‘x’ key

GetAsyncKeyState.call(0x58)

do stuff…

if GetAsyncKeyState.call(0x58) & 0x01 == 1
# we get here when the ‘x’ key was hit
end

See also GetKeyboardState and other related functions in the Win32 SDK
reference help.

that the socket thread won’t write anything on the screen (like a
warning message) if the prompt thread is waiting for a input.
