Finally got back. Sadly your newest crawl build (maemo8) doesn't work neither on phone, neither through PuTTY. Is there any setting that has to be changed for PuTTY to send \r on enter?
Oh, and the GL/U version is not stuck in the dungeon btw. I managed to get it to refresh the screen a few times (by turning phone with closed keyboard, locking/unlocking, ctrl-backspace) and it does accept input, but has some severe problems with displaying them. When I managed to get to help screen with text only it even was reacting for a bit. Also, the setting I hoped could help is for watching live games on server I believe, not tiles version, so this won't help
