dd_chat (formerly known as dd_ntalk-door) is a chat system derived from ntalk to be used with the DayDream BBS. The dd_chat client is a "door" program for the DayDream BBS that provides an easy-to-use chat client for the dd_chat server. Unlike the original ntalk client / server system, dd_chat implements several features from DayDream's libdd as well as an extended command set. It integrates seamlessly into DayDream. It features private conversation, checking for remaining BBS online time, chat idle timeouts (five minutes, except when in "away" mode), support for an ANSI logo and ANSI help screens from DayDream's "display" directory, and updating user status in DayDream.
