[[Image:Twimage.jpg|thumb|200px|[[ANSI art]] from the title screen of [[TradeWars 2002]]]][[Image:LegendOfTheRedDragon.gif|thumb|200px|Screenshot from [[Legend of the Red Dragon]] (LORD)]]A '''BBS door''' is a mechanism to execute and communicate with an external [[computer program|program]] (usually a [[computer game|game]], in which case it is also called a '''Door game''') on [[bulletin board system]]s.
The BBS software starts the external program, and the door system passes data back and forth between the door program, the BBS, and the remote user. To supply the door program with the user's information (such as the user's alias and the amount of time they had spent online), the BBS software creates a [[dropfile]] containing information for the program to read. A few door programs including Front Line operated the opposite way, as Front Doors, answering the modem and then giving control to the BBS software. This method was particularly commonplace for hubs of networks.
[[FOSSIL]] was a popular communications hardware/software interface standard used by MS-DOS compatible BBS software and door programs which has helped these legacy programs remain compatible with modern communications technologies such as [[Telnet]] and [[Rlogin]].
While many of the most popular and memorable BBS doors have been games, numerous doors had non-entertainment applications such as user polls or the [[time bank]], permitting users to time-shift their rationed BBS use. Frequently they would act as a front-end to themed databases on subject such as astrology, numerology and fortune-telling, recipes, weather prediction, personal ads (sometimes with additional match-making functionality), classified ads and "for sale" listings (sometimes permitting auctions), BBS lists and parting comments from the most recent BBS callers.
Prodoor provided a different message editor for use with the [[PCBoard]] messagebase. Many doors including Markmail and Qmail provided [[QWK (file format)|QWK]] functionality for convenient use with [[offline reader]]s. [[Sysop]]s who were away from the BBS computer sometimes called in and used DOORWAY by Marshall Dudley, which could run many DOS programs by modem, including [[file manager]]s, [[COMMAND.COM|DOS prompt]], and the specialized editing programs that administered the BBS. DOORWAY could also be utilized to safely (no drop to dos or diskwrites) make certain text mode dos games playable by bbs users using various command line switches.

* BBSList - Open Source ANSI Text Based Electronic Telephone Directory. Turning into a subroutine of a bigger... but as of yet not complete program known as BYTRONIX.EXE. Written in IBM Basic by Michael J. Bettua. Programming for BBSLIST.BAS started in the 1990's (1989 at the earliest) and came to a complete halt as soon as the original source code came up missing. The only known preserved copy was printed on an Okidata wide carriage printer.
