Subject: Re: How to read a single character from DOS prompt in windows (without <Enter>)?

This (or something like it) was posted a while ago by some helpfull
person (I forget their name). Its a win32 version.

require 'Win32API'

kbhit = Win32API.new("crtdll", "_kbhit", [], 'L')
getch = Win32API.new("crtdll", "_getch", [], 'L')
loop{
       puts " #{getch.Call.chr} pressed" if kbhit.Call != 0
       sleep 0.1
}
