Control characters in ruby

Ruby

Hello all,
I wanted to know how to accept control characters such as ESC, F1,
F2 from a command line in Ruby. I’m working on Opensuse (11.1) Linux.

Thank you so much. The solution for my case lies in ncurses or related
libraries (rbcurse, ffi-ncurses)…

FYI ruby has standard library support for curses. I don’t know if Suse
ships
their ruby with that feature compiled in but I’m sure they have it
somewhere
in their package system.
