Are you running in Windows or *nix. If you are on windows, you do not need termios for anything, so do not worry. If you are running *nix, a quick way to check if termios was installed properly is if the problem that requires termios is fixed or not. run examples/password.rb and jam on the keyboard very fast. If some keys leak through, then the termios gem probably did not install properly. If not, then you should be okay. This is the only known issue that seperates stty from termios as far as HighLine is concerned, therefore, if you aren't planning on using HighLine for passwords, you won't need it at all. It sounds like your issue is with termios, not HighLine, so I am not sure I can be of much help... if anyone else has the answer though, please post it. James is going to be mostly AFK for the next couple days, so if anyone has any HighLine questions they want to ask off list, feel free to email me: greg7224 at gmail dot com
