If you've never played nethack before, here are some instructions to get set up for this to work.
- Press 'c' to connect to the server.
- If you don't have an account then sign up for one through the terminal (The r key on the NAO landing screen)
- Enable the vt_tiledata option on your account. You can either manually edit your options and add the line 'OPTIONS=vt_tiledata'. If you don't know how options work and just want a starting options file, follow instructions 5-7 otherwise skip to 8.
- Login to the NAO website http://alt.org/nethack/
- Go to this page to edit your options file http://alt.org/nethack/webconf/nhrc_edit.php
- Copy this options file (Assumes you use the number pad) into the text area and then save
- Finally back on the terminal window, hit p to play the game after logging in
