Thanks! I tried it, but changing the font size doesn't seem to work. It DOES change the dimensions of the terminal, but it's not enough...

I get a message that says:

Your terminal size appears to be 131x27 characters. A 80x25 -sized terminal is REQUIRED for playing ADOM on this server. Please correct your terminal settings and try again. You may want to consult the readme, available at the main menu, and at http://ancardia.ath.cx/adom_server_info.txt

Any ideas?
